Question
P spends 22% of his salary on transportation, 30% on
food, 15% on children’s education and 25% on medical. He deposits the remaining amount of Rs. 640 in bank. How much total amount does he spend on transportation and food together?Solution
Remaining % of salary with P, => 100 – (22 + 30 + 15 + 25) = 8% So, => 8% --- 640 => 100% = (640/8) × 100 = Rs. 8000 Now, salary spent on transportation and food = (22 + 30)% of 8000 = Rs. 4160
