Question

The price of toys A, B, C are in the ratio 4 : 5 : 3 If the increments of 10%, 6% and 20% are allowed respectively in their prices, then what will be new ratio of their prices?

1. 44 : 53 : 36
2. 53 : 44 : 36
3. 36 : 55 : 44
4. Can't be determined 
5. None of these

Answer 1

Correct Answer - Option 1 : 44 : 53 : 36

Given:

Price of toys A, B, C are in the ratio 4 : 5 : 3

Increments of 10%, 5% and 25% are allowed respectively in their prices

Calculations:

Let A = 4x, B = 5x and C = 3x.

New price of toy A = (110/100) ​of 4x = (110/100) ​× 4x = (44/10)x​

New price of toy B = (106/100)​ of 5x= (106/100) × 5x = (53/10)x​

New price of toy C = (120/100)​ of 3x = (120/100​) × 3x = (36/10)x

⇒ New ratio (A : B : C) = (44/10)x ​: (53/10)x : (36/10)x = 44 : 53 : 36

∴ New ratio of their prices is 44 : 53 : 36
