Question
Twelve years from now, the combined ages of A and B
will be 94 years. Eight years ago, the ratio of the total of A and B's ages to the age of C was 3:2. Find the current age of C.Solution
Let present age of A, B and C is βxβ years, βyβ years and βzβ years. So, x + 12 + y + 12 = 94 So, x + y = 70 Sum of ages of A and C 8 years ago = 70 β 8 Γ 2 = 54 years Age of C, 8 years ago = 54/3 Γ 2 = 36 years Present age of C = 36 + 8 = 44 years

What will come in the place of question mark (?) in the given expression?
?% of (112 X 3 + 164) + 75 = 2 X 140 + 35
20% of 450 - 15% of 400 = 25% of ?
