  1.  ∛ 728.675 / ∛ 26.86 * 127.76 * ∛ 65 * ∛ 215.73 / √38 = ∛? – 22.24 * ∛ 215 / √26

1) 11             

2) 12   

3) 13   

4)14

5) 15

 

Answer & Solutions

Option: 2

Explanation:

∛729 / ∛27 * 128 * ∛64 * ∛216 /√36 = ∛? – 22 * ∛215 / √25

9/3 * 128 * 4 * 6/6 = ∛? – 22 * 5 / 5

1536 = ∛? – 22

∛? = 1558

? = 11.59             

?= 12

 

  1. 39% of 1755.25 + 80% of 241.12 + 49% of 1231.16 = ? ² + √ 36.20 + √ 80.95

40% * 1755 + 80% * 240 + 50% * 1230 = ?² + √ 36 + √ 81

702 + 192 + 615 = ?² + 6 + 9

1494 = ?²

? = 38.65

?= 39
