Question
A group of 'x' men can finish a job in 46 days. If 8
additional men had joined the group, they could have completed the same job 16 days earlier. Assuming all men work at the same efficiency level, determine the value of 'x'.Solution
Let efficiency of each man = βMβ units/day ATQ, (x Γ M Γ 46) = {(x + 8) Γ M Γ (46 β 16)} Or, 46x = 30x + 240 Or, 16x = 240 Or, x = (240/16) = 15
(22Β Γ 52 ) + 4 Γ 6 = ? - β324
What should come in place of (?) question mark in the given expression.
Β (25% of 320) + (3/8 of 400) β 30 = ?
(5832)1/3 Β Γ 10.11 Γ 11.97 Γ· 16.32 = ?Β + 45.022
82% of 400 + √(?) = 130% of 600 - 85% of 400
If (x + 1/x) = 5, then value of x3 + 1/x3 is:
Simplify: (1 Γ· 0.08)
What should come in place of (?) question mark in the given expression.
{ (144 Γ· 12) Γ 5 } β (18 Γ· 3) = ?
Simplify the following expressions and choose the correct option.
(3/4 of 256) + (2/5 of 150) - (72 Γ· 7)
464 + 181 +? = (154 Γ 25) - (15) 2 Β
15% of 1800 + 22 = ?Β
