Answer 1

Answer:

RS 5625

Step-by-step explanation:

Correct Option: B

The ratio of the saving = 6 : 8 : 5

 

So the saving of Ramesh, Suresh and Dinesh is 6x, 8x, 5x.

 

The saving of Ramesh is (100 – 70)% = 30% that is 6x. So the income is 6x ÷ 30 × 100 = 20x

 

The saving of Suresh is (100 – 75)% = 25% that is 8x. So the income is 8x ÷ 25 × 100 = 32x

 

The saving of Dinesh is (100 – 80)% = 20% that is 5x. So the income is 5x ÷ 20 × 100 = 25x

 

Total income = 20x + 32x + 25x

 

17325 = 77x

 

x = 225

 

Dinesh’s income = 25 × 225 = Rs. 5625
