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.
A:B:C
2:3:5.

Here, the value of A, B and C is 2:3:5 respectively, and increments are 15%, 10% and 20% so for the new ratio,
(15/100*2 +2) : (10/100*3+3) : (20/100*5+5).
(3+20/10) : (3+30/10) : (5+1).
23/10:33/10:6.
23 :33 : 60.
(15/100*2 +2) : (10/100*3+3) : (20/100*5+5).
(3+20/10) : (3+30/10) : (5+1).
23/10:33/10:6.
23 :33 : 60.

Just let ratio 20:30:50 {easy to calculate}
Calculate increment = 15% of 20 is 3 so the new ratio is 20+3 = 23.
10% of 30 is 3 = 30+3 = 33,
20% of 50 is 10 = 50+10 = 60.
New ratio after increment = 23 : 33 : 60.
Calculate increment = 15% of 20 is 3 so the new ratio is 20+3 = 23.
10% of 30 is 3 = 30+3 = 33,
20% of 50 is 10 = 50+10 = 60.
New ratio after increment = 23 : 33 : 60.
