Question
Virendra invested Rs. 2600 at 20% p.a. simple interest
for 3 years. After 3 years, he invested the amount received by him at the 20% p.a. compound interest, compounded annually for another 2 years. Find the final amount received by Virendra at the end of 5 years.Solution
Amount received by Virendra after 3 years of investment = (2600 × 20 × 3)/100 + 2600 = Rs. 4160 Therefore, sum invested by Virendra at compound interest = Rs. 4160 Amount received by Virendra at the end of 5 years = 4160(1 + 0.2)2 = Rs. 5990.4
1500 × 60% of 25% = ? 2
[1.45 X 1.45 X 1.45 + 0.55 X 0.55 X 0.55 + 4.785] = ?
72 + 122 - 25% of 600 = ?
22 * 6 + 45% of 90 + 65% of 180 = ?
- What will come in place of (?) in the given expression.
√324 + √121 – √49 = ? 5.5 × 3.2 × 2.3 = ?
What will come in the place of question mark (?) in the given expression?
(√676 of √144 ÷ 13) of 2400% = ?
65% of 102 + 14 = ? – 20
? = √2704 ÷ (25% of 104) + 73
375% of 320 - 80% of 40 ÷ √256 = ?
