Question
When 14 years is subtracted from the present age of A
and the obtained result is divided by 2, then the present age of his nephew is obtained. If the present age of his nephew is 5 years less than the present age of Aβs son who is 16 years old, then find the present age of A.Solution
Let the Present age of A be βxβ years Present age of his nephew = 16 β 5 = 11 years Therefore, {(x β 14)/2} = 11 Or, x β 14 = 22 Or, x = 36 Therefore, present age of A = 36 years
(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
