11.

The salaries A, B, C are in the ratio 2 : 3 : 5. If the increments of 15%, 10% and 20% are allowed respectively in their salaries, then what will be new ratio of their salaries?

Answer: Option

Explanation:

Let A = 2*k*, B = 3*k* and C = 5*k*.

A's new salary = | 115 | of 2k = |
115 | x 2k |
= | 23k |
||

100 | 100 | 10 |

B's new salary = | 110 | of 3k = |
110 | x 3k |
= | 33k |
||

100 | 100 | 10 |

C's new salary = | 120 | of 5k = |
120 | x 5k |
= 6k |
||

100 | 100 |

New ratio | 23k |
: | 33k |
: 6k |
= 23 : 33 : 60 | ||

10 | 10 |

@All.

A:B:C

2:3:5.

Increments are 15%, 10%, 20% Happen

So we have to find out their new salaries,

A= (2 * 0.15)=0.3 So add this in first ratio.

Then 2+0.3=2.3

Similarly B = (3 * 0.1)=0.3,

B = 3+0.3=3.3,

C =( 5 * 0.2)=1,

C = 5+1,

So the Ratios are now 2.3 : 3.3 : 6,

After multiplying with 100 in each;

= 23:33:60.

115/100*20:110/100*30:120/100*50.

= 23:33:60.

Here 2=20 and 3=30 and 5=50.

= 23:33:60.

Here 2=20 and 3=30 and 5=50.

How 23/10:33/10:6 = 23:33:60?

115*2/10=23,

110*3/10=33,

120*5/10=60.

So, 23:33:60.

110*3/10=33,

120*5/10=60.

So, 23:33:60.

2*1.15, 3*1.1,5*1.2.

2.3, 3.3, 6

23, 33, 60.

2.3, 3.3, 6

23, 33, 60.

Can anyone tell me how you can solve 23k/10 : 33k/10 : 6x into 23k : 33k :6k?

Please explain.

Please explain.

Why the 10 and x gets cancelled in above question of Ratio and Proportion?

20*115/100 = 23,

30*110/100 = 33,

20*120/100 = 60.

23 : 33 : 60.

30*110/100 = 33,

20*120/100 = 60.

23 : 33 : 60.

It can be solve in ay method:

2 * 115 : 3 * 11 : 5 * 120.

= 2 * 23 : 3 * 22 : 5 * 24.

= 23 : 33 : 60.

2 * 115 : 3 * 11 : 5 * 120.

= 2 * 23 : 3 * 22 : 5 * 24.

= 23 : 33 : 60.
