Let total number of subjects be x. Then, => (60x + 26 + 19)/x = 65 => 60x + 26 + 19 = 65x => 5x = 45 => x = 9
(-251 × 21 × -12) ÷ ? = 158.13
23 × 20 + ? = 182 + 92 + 82
35 × 540 ÷ 18 of 15 – ? = 15
68% of 450 – 1008 ÷ 14 + 516 ÷ 43 =?
25% of (?) + (1/4)of 5600 = 2500 – 20% of 1940
1540 ÷ 7 - 184 ÷ 8 = ?
2/5 of 3/4 of 7/9 of 7200 = ?
? = 0.05% of 12000 + 175% of 4800 – 133
(? + 2180) ÷ 69 × 5 = 450
(√529 + 63 /8)% of 800 = ?% of 250
