Question
The average of 5 numbers is 24. If one number is
removed, the average of the remaining 4 numbers becomes 21. Find the number that was removed.Solution
Sum of 5 numbers = 5 Γ 24 = 120 Sum of remaining 4 numbers = 4 Γ 21 = 84 Number removed = 120 β 84 = 36 Answer: 36
- What will come in the place of question mark (?) in the given expression?
(198/13) X (52/11) - ? Γ· 5 = 13 + 68 Γ· 4 What will come in the place of question mark (?) in the given expression?
β4096 + β3249 = (?)2
Simplify the following expressions and choose the correct option.
Β (96 Γ· 8 + 72 Γ· 9) * 3
((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?
{(5/8) + (4/5)} Γ (?/19) = 33
(72 × 52 + 1555 )/(79+60) = 2000 ÷ ?
What will come in the place of question mark (?) in the given expression?
25% of 1280 + (41 Γ 4) = ?2Β
