Question
A man invests ₹50,000 in a scheme offering compound
interest at 10% per annum, compounded annually. He withdraws ₹25,000 after 2 years. If he lets the remaining amount grow for another 2 years, what will be the final amount in the account?Solution
Amount after 2 years = ₹50,000 × (1 + 10/100)² = ₹50,000 × 1.21 = ₹60,500. After withdrawal, remaining principal = ₹60,500 - ₹25,000 = ₹35,500. Final amount after 4 years = ₹35,500 × (1 + 10/100)² = ₹35,500 × 1.21 = ₹42,955. Correct option: D
√ [? x 11 + (√ 1296)] = 16
? = 6.25% of 240 + 252 + 172 – 16 × 17
436 × 794 – 68210 =? + 85730
?/4 ÷ 9/? = 15% of 800 + `1(2/3)` × `1(1/5)` × 1/2
16 × 14 + 30 × 21 = 14 × ?
60% of 250 + 14 × 10 - 210 = ?
What will come in the place of question mark (?) in the given expression?
30% of 520 + 16% of 1500 = ? + 244
33 × 5 - ?% of 250 = 62 - 6
140% of 9/8 of ? = 108% of 2800
