Question
Anchal allocates 20% of his monthly salary to
transportation, dedicates 50% to shopping, and invests 20% of the remaining balance in food expenses. The remaining amount is saved in mutual funds, yielding a simple interest at a rate of 10% per annum. Determine the total amount Anchal will possess at the end of the year, given that he spends Rs. 1200 per month on food.Solution
ATQ, Let, monthly Salary = Rs. 100a Spending on Transportation = 100a × 0.2 = Rs. 20a Spending on Shopping = 100a × 0.5 = Rs. 50a Spending on Food = (100a – 20a – 50a) × 0.2 = Rs. 6a Savings in Mutual funds = 100a – 50a – 20a – 6a = Rs. 24x Now, 6a = 1200 Or, 24a = 4800 Total interest paid by recurring scheme = P. r. n (n + 1)/(2 × 12 × 100) = 4800 × 12 × (12 + 1) × 10/(2 × 12 × 100) = Rs. 3120 Amount = 4800 × 12 + 3120 = Rs 60720
40.5 ÷ [4/5 of (32 + 18) - 29/2] = ? ÷ 102
(1/2) – (3/5) + 3(1/3) = ? + (5/6)
(350/?) = 23 + 33
25% of 250 + 32% of 200 = ? ÷ √ 16
? = 20% of 1200 + 256
21% of 400 − 150 = ? − 77
172Â - 92Â + 121 - 74 = ?
24% of 150% of 500 + 140 = ? × 8Â
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
? = 65% of 40% of (20 × 250) − 200
