P spends 30% of his salary on transportation, 25% on
food, 28% on children’s education and 10% on medical. He deposits the remaining amount of Rs. 490 in bank. How much total amount does he spend on transportation and food together?Solution
Remaining % of salary with P, => 100 – (30 + 25 + 28 + 10) = 7% So, => 7% --- 490 => 100% = (490/7) × 100 = Rs. 7000 Now, salary spent on transportation and food = (30 + 25)% of 7000 = Rs. 3850
