Direction (Q. 1 - 10) : What should come in place of the question mark (?) in each of the following questions ?
3/7 + 1/2 ÷ {(1/2 x 2 - 10) fo -1/4} = ?
3/7 + 1/2 ÷ {(1/2 x -8) of (-1/4)}
3/7 + 1/2 ÷ {-4 of -1/4}
3/7 + 1/2 ÷ 1 = 3/7 + 1/2 = 13/14
(41653 - 31613) ÷ 20 = ?
No Explanation
15 66/7 - 5 3/4 + 16 7/6 = ?
15 6/7 - 5 3/7 + 16 7/6 = more than 26
None of the choices match this value.
142 + 12 x 1.25 - 23 = ?
142 + 12 x 1.25 - 23
= 142 + 15 - 23
= 157 - 23 = 134
(95.95)2 - (64.05)2 = ?
(95.95)2 - (64.05)2
= (95.95 + 64.05)(95.95 - 64.05)
= 160 x 31.9 = 5104
(89)3 = ?
12.5% of 1200 x 7.5% of 750
150 + 56.25
3.73 x 3.73 - 9.1758 + 1.5129/0.25 = ?
(3.73 x 3.73) - 2 x 3.73 x 1.23 + (1.23 x 1.23)/25
= (3.73 - 1.23)2 /25 = (2.5)2 /25 = 25
[3√343 x (√3√81x9)2]2 = ?
[7 x 9]2 = (63)2 = 3969
13.64 + 76.79 - 26.43 = ?
