Total age of 20 girls = 20 ×12 = 240 years Total age of 24 girls = 240 + (4×9) = 276 years Therefore new average age = 276/24 = 11.5 years
Calculate the simplified result of the following expression: 12 × 18 ÷ 3 + 36 of 32 ÷ 3
The value of {5 − 5 ÷ (10 − 12) × 8 + 9} × 3 + 5 + 5 × 5 ÷ 5 of 5 is:
(60 × 8 ÷ 10) × 5 = ?
110 ÷ 5.5 + (?)3 ÷ 12 = 20(2/3)
25% of {(5/18) × 2880 + 122 } = ?% of 590
60% of 250 + 14 × 10 - 210 = ?
[16 × 15 + 224 × 5] ÷ 5 = ? × 4
15 × 35 ÷7 + 60% of 300 =?
(22 × 52 ) + 4 × 6 = ? - √324
What will come in the place of question mark (?) in the given expression?
(70 × 8 ÷ 10) × 5 = ?
