Question
If 236 = 33, 487 = 57, 6391 = 57, then 851 =
?Solution
The logic followed here is as follows: The sum of all the digits of the number, and then the sum is multiplied by '3'. For 236 = 33: 2 + 3 + 6 = 11×3 = 33 For 487 = 57: 4 + 8 + 7 = 19 × 3 = 57 For 6391 = 57: 6 + 3 + 9 + 1=19 × 3 = 57 Similarly, for 851 = ?: 8 + 5 + 1 = 14 × 3 = 42
What will come in the place of question mark (?) in the given expression?
25% of 1280 + (41 × 4) = ?2
672 ÷ 28 × 24 + 363 – 309 =?
What should come in place of (?) question mark in the given expression.
65% of 460 − (3/4 of 160) = ?
4567.89 - 567.89 - 678.89 = ?
9999² + 1111² =?
[3/5 of (31 + 44) – 10] ÷ 7 = ?
7292/3 = ?
116*2/3% of 18600 + 666*2/3% of 1290 = 457*1/7% of 1750 + 555*5/9% of 3150 + ?
15% of 695 – 12.5% of 250 =? – 1200
Simplify the following expressions and choose the correct option.
{[(96 ÷ 3) × (5/8)] + 7²} ÷ 9 = ?
