Water cement ratio = wt.of water/wt. of cement. = 30/50 = 0.60. |

Sachin said: (Jan 24, 2015) | |

Volume of 1 bag cement is 35 l. Option D is correct. = 30/35. |

Gautam said: (May 28, 2015) | |

Volume of 1 bag cement is 50. So option C is correct. |

Shanker Lal Meghwar said: (Jun 17, 2015) | |

Volume of 1 bag of cement = 50 Kg or 35 liters. Given amount of water is in liters i.e. 30 liters. For finding W/C ratio units must be homogeneous. Therefore: W/C = 30/35 = 0.86. So, option "D" is correct. |

Deva Aj said: (Sep 13, 2015) | |

Both the materials should be considered in same units. Therefore, volume of 1 bag of cement in liters is = 35. W/C = 30/35 (in liters). = 0.86. Option "D" is the correct answer. |

Srinivas said: (Oct 14, 2015) | |

Volume of one bag = 0.035 cu.m. |

Patel Siddharth said: (Nov 26, 2015) | |

Cement 1 bag weight 50 kg. Water is 30 liter. W(Water)/C(Cement) = 30/50 = 0.6. Option 'C' is the correct answer. |

Vikas said: (Jan 28, 2016) | |

30 liter/35 liter = 0.86. |

Rhijul Sood said: (Mar 17, 2016) | |

Wt of 30l water = density * Volume = 1000 kg/m3 * 30*10^-3 m3 = 30 kg. W/c = 30/50 = 0.6. |

Zahir said: (May 30, 2016) | |

Water cement ratio is based on Weight Ratio. So we would find the 30 litres = 30 kg and that's why the answer is C. |

Samadhan Chaudhari said: (Nov 2, 2016) | |

Guys, 35 ltr is the volume of 1 bag of cement. The water cement ratio is calculated by considering the weight of both materials. So the weight of 1 cement bag is 50kg. And weight of water is 30 litre equal to 30kg. Ratio will be 30/50 = 0.6 |

Abhiraj said: (Nov 15, 2016) | |

Hi, The Correct answers is 0.6. Water cement ratio = weight of water/ weight of cement. The weight of 1-litre water is 1 kg. So, 30 liter = 30 kg. Weight of 1 bag cement (volume = 35 liter) is 50kg. Therefore, W/c ratio = 30/50 = 0.6. |

Ranjan said: (Dec 26, 2016) | |

C is the correct answer. I agree. |

Safee said: (Dec 27, 2016) | |

1 BAG = 35 LITRES = 50 KG. For finding W/C ratio units, W/C = 30/35 (in liters). = 0.86. Option "D" is the correct answer. |

Rohit Kumar said: (Jan 23, 2017) | |

Only option C is correct, because normal range wc ratio is 0.4 to 0.6. |

Mudasir said: (Feb 16, 2017) | |

Can anybody will confirm me what is the correct answer. 0.6 or 0.86? I read book, some are saying water cement ratio is measure of wt of water/ wt of cement, and some are saying wt of cement/ volume of cement. So, if anybody knows please post it. |

Ankush said: (Mar 30, 2017) | |

C is the correct answer. I agree with the given answer. |

Anil Kumar said: (Mar 31, 2017) | |

The water cement ratio is taken as ( volume of water/weight of cement). So, the answer given is correct. |

Sudhakar said: (Apr 22, 2017) | |

w/c ratio should be in units of weights only. Hence, 30lit water=30kg of water. 50kg cement. W/c = 30/50 = 0.6. |

Hir said: (May 2, 2017) | |

1lit = 1kg so w/c ratio is; W/c = 30/50 = 60. |

Souvik Sadhukhan said: (May 9, 2017) | |

WE KNOW W/C RATIO = WEIGHT OF WATER / WEIGHT OF CEMENT. AND WE ALSO KNOW 30 LTR WATER = 30 KG WATER. THEN W/C RATIO = 30/50 = 0.6. |

Vijay Vikram said: (Aug 3, 2017) | |

Water cement ratio = wt.of water/wt. of cement. = 30/50 = 0.60, Option c is correct. |

Vikas said: (Aug 26, 2017) | |

Since, the density of water =1kg/L. (W/C) the ratio is taken in weight not in volume. Wt of 30L of water = 30 kg. And, w/c =30/50=0.6. So, C is correct. |

Sandeep Singh Yadav said: (Jan 25, 2018) | |

1 bag cement= 34.5L. Again so w:c= 30L/34.5L, = 0.86. So Correct option is :-D. |

Govardhan said: (Apr 15, 2018) | |

Here ask only water-cement ratio but you have said density of 1bag of cement so, water cement ratio of 1bag cement is 0.60, 1bag=50kg, 50/30=0.60. |

Ramesh said: (Apr 22, 2018) | |

30/50 = 0.60 is the correct answer. |

Hariman Meena said: (Jun 2, 2018) | |

C is right. Because of a density of water is 1kg/lit. So 30kg=30Lit. |

Amit Bhandari said: (Sep 27, 2018) | |

Since Water cement ratio = weight of water/weight of cement. (Note: the unit of weight is kg and unit of volume is lit) The weight of 1 bag (vol -35 lit or 0.035 CuM) of cement is= 50kg. The weight of 30 lit of water = 30 kg (since the density of water is 1kg/lit). Therefore, W/C ratio = 30 kg(weight)/50 kg (weight) = 0.6 (Answer). Option 'C' is the right answer! |

Deepak said: (Oct 16, 2018) | |

The density of water is 1000kg/m^3. And 1 m^3 equals to 1000 litres. 1 litre of pure water has a weight of 1 kg. We know that the density of pure water is 1000 k g/m 3. It means 1 cubic meter of pure water has a weight of 1000 kg. |

Cb Singh said: (Dec 7, 2018) | |

Water cement ratio is weight ratio of water & cement. |

Vicky said: (Dec 24, 2018) | |

The water-cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. So 30/50=0.6 (option C is correct). |

Babita said: (Jan 9, 2019) | |

w/c ratio is the weight of water to weight of cement not the volume of cement. So, 30/50 =0.60. 1 bag of cement is 50 kg & 35 ltr. |

Sunil said: (Jul 9, 2019) | |

W/c ratio is measured in kg/l, so option C is correct. |

Sable said: (Jul 25, 2019) | |

W, c ratio is 60. |

Chetan said: (Nov 14, 2019) | |

W/c ratio is measured in lit/kg. Answer must be C. |

Arvind Singh Rawat said: (Jan 23, 2020) | |

Density of water =1000kg/m3. volume of water = 30 litres = 30/1000 m3. weight of water = 1000 x 30 /1000 = 30kg. W/C ratio = 30/50 = 0.6 So, option C is correct. |

Akshay Kumar P said: (Mar 3, 2020) | |

Wt of 1bag cement = 50 kg. Wt of 30litre water = 30 kg. Wc ratio = wt of water /wt of cement = 30/50. Wc ratio = 0.6. |

Santosh said: (Dec 26, 2020) | |

Great, Thanks @Abhiraj. |
