Question
Which of the following numbers is divisible by
11?Solution
3649285: Difference = (3 + 4 + 2 + 5) – (6 + 9 + 8) = 14 – 23 = 9
2517846: Difference = (2 + 1 + 8 + 6) – (5 + 7 + 4) = 17 – 16 = 1
1938427: Difference = (1 + 3 + 4 + 7) – (9 + 8 + 2) = 15 – 19 = 4
7428516: Difference = (7 + 2 + 5 + 6) – (4 + 8 + 1) = 20 – 13 = 7
None of them is divisible by 11.
What value should come in place of (?) in the given expression.
450 ÷ 9 + 75% of 160 − 64 ÷ 4 = ?
2/5 of 3/4 of 7/9 of 14400 = ?
7/3 of 4/5 of 15/56 of ? = 83
[564 + 32 of 18 × 9 ÷ 12 + 162 ] ÷ 4 = ?
What should come in place of (?) question mark in the given expression.
(25% of 320) + (3/8 of 400) − 30 = ?
45% of 360 - 160 + ? = √324
187 ÷ 5 ÷ 0.4 = ? – 24 × 2.4
Find the simplified value of the following expression:
[{12 + (13 × 4 ÷ 2 ÷ 2) × 5 – 8} + 13 of 8]
18 × 15 + 86 – 58 =? + 38
√(24²+285-8²-172) = ?²
