Direction (Q. 1 - 5) : What should come in place of the question mark (?) in the following question ?
{(147)2 ÷ 21 x 9} ÷ 21 = 120 x ? + (?)4
147 x 147 x 9/21 x 21 = 49 x 9
= 441 = 120 + (3)4
(3)27 ÷ (9)11 x (81)7 ÷ (243)6 = (3)?
327 ÷ (32)11 x (3)28 ÷ (3)30
= (3)27+28-11-30 = 33
46368 ÷ ? = 46 x 48
? = 46368/46x48 = 21
25.4% of 500 - 16.9% of 250 = 25% of ?
25.4x500/100 - 16.9 x 250/100
= 127 - 42.25 = 84.75 = 25% of 339
14/13 of 18/17 of 1/21 of 3/35 of 54145 = ?
No Explanation
Direction (Q. 6 - 10) : What approximate value should come in place of the question mark (?) in the following questions ?
499.01 + 306 x 13.009 = ?
? = 500 + 306 x 13 = 500 + 3978 = 4478
(10005.66)2/10004.001 x √3256 x 1.0001 = ?
? = (10006)2/10004 x 57 x 1
= 100120036x57x1/10004 = 570456
(199.99999)3 = ?
? = (199.99999)3
= (200)3 = 8000000
2070.01 ÷ 12.00 + 29.991 x (3.999)2 = ?
? = 2070 ÷ 12 + 30 x (4)2
= 173 + 480 = 653
(86)2 ÷ 3√29791 = ?
? = (86)2 ÷ 3√29791
= (86)2 ÷ 31 = 7396 ÷ 31 = 240
