Question
'T' spends 20% of his monthly income on education, 35%
on medical expenses, and 15% of the remaining amount on leisure activities. He saves the rest in a bank deposit that gives simple interest at a rate of 7% per annum. Find the amount 'T' will get at the end of the year if his spending on leisure activities is Rs. 750 per month.Solution
Let monthly income = Rs. 100b Spending on education = 100b × 0.2 = Rs. 20b Spending on medical expenses = 100b × 0.35 = Rs. 35b Spending on leisure activities = (100b – 20b – 35b) × 0.15 = Rs. 6.75b Savings = 100b – 20b – 35b – 6.75b = Rs. 38.25b Now, 6.75b = 750 Or, 38.25b = 4250 Total interest paid by the bank deposit: = P × r × t = 4250 × 7 × 1/100 = Rs. 297.50 Amount = 4250 + 297.50 = Rs. 4547.50
[{70 + (40 - 22) ÷ 3} ÷ 4] = ?
? % of 1200 = 20% of 30% of 3600
√ (96 + 1000 + 3000) = ?
Solve the following:
1500 ÷ (9 × 18 ÷ 6 × 3 – 45) ²
(7/5) × (3/4) × (5/9) × (6/7) × 3112 = ?
What will come in the place of question mark (?) in the given expression?
(125 × 64) ÷ (8 × 5) + (12.5)² – (144 ÷ 3) = ?
...?2 - (40% of 240) = 25 X 5
5.5 × 3.2 × 2.3 = ?
