Question
In a company team of 18 members, the average age is 29
years. When 6 more members join, the average age falls to 26. What is the average age of the new members?Solution
Initial sum = 18 × 29 = 522 years
New team = 24
New average = 26
New total = 24 × 26 = 624 years
Sum of new = 624 - 522 = 102 years
Average = 102 ÷ 6 = 17 years
What will come in the place of question mark (?) in the given expression?
(11/45) of 225 + 3 X 75 = ? X (72 ÷ 6 + 4)
654.056 + 28.9015 × 44.851 – 43.129 = ?
9/5 × 18/25 ÷ 42/21 = ? - 82/75
1500 ÷ 15 + 1000 ÷ √100 + ? = 250 * 3
[4(1/3) + 4(1/4)] × 24 – 62 = ?2
25% of 30% of 3/5 of 14500 =?
555.05 + 55.50 + 5.55 + 5 +0.55 = ?   Â
50 ÷ 2.5 × 64 + ? = 1520
2856 ÷ 34 = ?% of 240
18/2 of 3/9 of 2/6 of 69690= ?
