55.55% of 30000 – 1111 = ? × 1111
(? + 180 + 13 × 6) ÷ 20 + 3.5 × 512 (1/3) = 82
30% of 600 –
(512) (2/3) × √64 ÷ (512) (1/3) = (64) (?/2) ÷ (2)6Â
(392 + 427 + 226 – 325) ÷ (441 + 128 – 425) = ?Â
What value should come in the place of (?) in the following questions?
53 × 12 + 43 × 13= ? × 7 - 12% of 1300
1.25 × 36 + 2.75 × 40 = ? × 3.1
45% of 360 - 160 + ? = √324
(2/?) x (3/16) x (2/15) x 60 = 1/3 Â
