Rice at Rs 80/kg is mixed with rice at Rs.40/ kg in a certain ratio such that by selling the mixture at Rs.60/ kg profit of 20% is made. If the quantity of 1st type of rice is 75 kg, find quantity of type of rice?
S.P Of the quantity = Rs.60/kg C.P of the quantity = 60/120×100 = Rs.50 Now ,Solve with Allegation 
Quantity for 1st = 75 kg Therefore, Quantity for 2nd = (75)/(1×3) = 225 kg.
[(15)³ × (8)²] ÷ (90 × 6) = ?²
2856 ÷ 34 = ?% of 240
9 × 40× 242 × 182= ?2
(6 × √361) × 2.5 = ? + 125
255 × 8 + 386 × 5 =? % of 7940
1111.25 × 9.05 + 2323.23 × 9.05 – 2121.37 ×9.05 =?
40% of 1820 + 80% of 630 = 90% of 1280 + ?
If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
25% of 140 + 2 × 8 = ? + 9 × 5
