4. 15% 
5. None of these

Answer 1

Correct Answer - Option 3 : 10% 

Given 

Suresh's income is less than Ekram income = 30% 

Raju's income is less than Ekram income = 37% 

Formula Used 

Percentage = (Actual/Total) × 100

Calculation 

Let the Ekram Income be 100x 

Suresh's income = 100x - 30% of 100x = 70x 

Raju's income = 100x - 37% of 100x = 63x 

Raju's income is less than Suresh income = 70x - 63x = 7x 

Percentage Raju's income is less than suresh income = (7x/70x) × 100 = 10% 

∴ Raju's income is less than suresh income by 10%
