P started a business with an investment of Rs.10000, after 8 months Q joined him with Rs.15000 and after another 8 months R joined them with Rs.20000. If after end of two years profit share of Q is Rs.9600, then what is the total profit earned by them?
Ratio of profit share of P, Q and R = 10000 x 24 : 15000 x 16 : 20000 x 8 = 3:6:4 Required amount = 9600 x (13/6) = Rs.20800
108² + 99 X 98² =?
...28(4/5) + 52(1/2) × 8(2/7) - 11(1/5) = ? + 6(1/5)
30, 39, 66, ? , 174, 255
25% of 60 × 15% of 120 = 30% of (?)
{(80% of 650 + 25 × 12) – 20 × ?} = 760
360 × 9 ÷ 3 + 120 + 900 ÷ 5 = ?
(18% of 360) ÷ 0.4 = ?
44% of 1250 + 46 × 34 = 40% of ? + 1154
89 ÷ 512 × (1/64) = (23)?
