Monthly instalment = Rs. 2,500 Total loan = Rs. 20,000 ∴ Number of instalment = 20,000/2,500 = 8 Once the payment starts outstanding balances will go on diminishing. Hence, from point of view of interest, principal = 20,000 + 17,500 + 15,000 + 12,500 + 10,000 + 7,500 + 5,000 + 2,500 = Rs 90,000 ∴ Interest on Rs. 90,000 for 1 month at 16% p.a. = (90,000 × 16 × 1)/(100 × 12) = Rs. 1,200 Average rate of interest = (100 × I)/(P × T) T = 8 months = 8/12 year = (1200 × 100 × 12)/(20,000 × 8) = 9%
Find the approximate value of Question mark(?) for given equation.
(71.92% of 149.99) ÷ 12.04 + 107.98 = ?
12.99% of 499.99 ÷ 13.17 = ? ÷ 20.15
(2310.23 ÷ 32.98) + (1008.32 ÷ 23.9) + 1594.11 = ?
?% of 549.83 – 18.05 × 31.96 = 44.94% of 479.84 – 13.98 × 33.13
19.87% of (49.68 × ?) = 19.78% of 1099.87
A can complete a piece of work in 15 days. B is 30% more efficient than A. If they work together, how many days will it take to complete the work?
30.11% of 149.99 + √195.97 ÷ 7.02 = ?
1560.182 ÷ √168 + √143 * √224 – 4649.87 ÷ 30.883= ?
(3/5) of 3025 + (18² + 12²) = ? + 22.22% of 1125
