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 = 2k, B = 3k and C = 5k.
| 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.
