Find the ratio between the expenditure of C and the expenditure of D.
Required ratio = (27500 – 8000) : (30000 – 10000) = 39:40
447.8× 441.2÷ 445= 44 × 44?
5 × 14 + 100 ÷ 4 = 62 + ?
√529 + √64 + 92 = ?
?% of 120 × 3√343 = 42 × 20
36 x 3.6 ÷ 0.5 ÷ ? = 64
(115 × 17 × 3)/(23 × 51) + ?3 = √169
4567.89 - 567.89 - 678.89 = ?
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
(√121 + √196) × 7 =? × 5
96% of 4500 – 34% of 650 = ?
