Alexander Fleming discovered penicillin in 1928.
25.6% of 250 + √? = 119
What is 12% of 4% of 7% of 2 x 106 ?
4368 + 2158 – 596 - ? = 3421 + 1262
(60/15) × 25 + 15 2 – 18% of 200 = ? 2
The value of 42 ÷ 9 of 6 - [64 ÷ 48 x 3 – 15 ÷ 8 x (11 – 17) ÷ 9] ÷ 14 is:
(13 X 11) + (19 X 3) = 400% of √?
(5/8 + 7/12) x 168 = ? + 93 - 25
{(522 – 482 ) ÷ (27 + 73)} × 35 = ?% of 17
(15 × 16) + 242= ? × 16
