ATQ, Amount = Principal × (rate/100) × time + Principal So, amount = 4,000 × (25/100) × 3 + 4,000 Or, amount = Rs. 7,000 Using, A = nx + [(n - 1) + (n - 2) + .... + 1] × Rx ÷ 100 Where, 'A' is the amount, 'n' is the time, 'x' is the amount of each installment and 'R' is rate of interest So, 7,000 = 3x + (2 + 1) × 25x ÷ 100 Or, 7,000 = 3x + 0.25x Or, 7,000 = 3.25x Or, 'x' = (7,000/3.25) ~ 2,154 Therefore, amount of each installment is Rs.2154 (approx.) .
3/7 Of 504 ÷ 12 + 17 = √?
436 × 794 – 68210 =? + 85730
(47.5 ÷ 9.5) × (78.5 ÷ 15.7) + 475 = ? + 15% of 150
(?)2 = {(26% of 35% of 3000) ÷ 3} × 91
22.5% of 300 + 32.5% of 4500 =?
25.6% of 250 + √? = 119
375% of 320 - 80% of 40 ÷ √256 = ?
1280 ÷ 8 + 490 ÷ √49 + ? = 150 * 2
