Question
P spends 26% of his salary on transportation, 24% on
food, 22% on children’s education and 19% on medical. He deposits the remaining amount of Rs. 540 in bank. How much total amount does he spend on transportation and food together?Solution
Remaining % of salary with P, => 100 – (26 + 24 + 22 + 19) = 9% So, => 9% --- 540 => 100% = (540/9) × 100 = Rs. 6000 Now, salary spent on transportation and food = (26 + 24)% of 6000 = Rs. 3000
