P spends 27% of his salary on transportation, 30% on food, 18% on children’s education and 16% on medical. He deposits the remaining amount of Rs. 720 in bank. How much total amount does he spend on transportation and food together?
Remaining % of salary with P, => 100 – (27 + 30 + 18 + 16) = 9% So, => 9% --- 720 => 100% = (720/9)×100 = Rs. 8000 Now, salary spent on transportation and food = (27 + 30)% of 8000 = Rs. 4560
