Question
Rs. 5000 when invested at simple interest of r% p.a.
amounts to Rs. 6000 in 24 months. If the same sum had been invested for 1 year at compound interest of (r + 20) % p.a. (compounded in every 4 months), then the amount received would be?Solution
According to the question, 6000 – 5000 = (5000 × r × 24) ÷ (12 × 100) Or, 1000 = 100 × r Or, r = 10 When the sum is invested at compound interest, Effective rate of interest = (r + 20) ÷ 3 = (10 + 20) ÷ 3 = 10% Effective time period = 1 × 3 = 3 units Amount received = Principal × {1 + (r/100)}time period = 5000 × {1 + (10/100)}3 = 5000 × (1.1)3 = 6655
2945 – 1508 + 3454 = ? + 2255
13/3 – (23/6) = ? – (22/9)
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
What will come in the place of question mark (?) in the given expression?
√1936 + (84 ÷ 2 × 1.5) – 35² + 18² = ?
1440 ÷ 12 + 540 ÷ √36 + ? = 180 * 3
(√7225 x √1225)/(√625) = ?
(1520 - 1350) ÷ (550 – 500) = ?
