Question
Which of the following numbers is divisible by
11?Solution
8463729: Difference = (8 + 6 + 7 + 9) – (4 + 3 + 2) = 30 – 9 = 21
6938254: Difference = (6 + 3 + 2 + 4) – (9 + 8 + 5) = 15 – 22 = 7
2471865: Difference = (2 + 7 + 8 + 5) – (4 + 1 + 6) = 22 – 11 = 11
3527164: Difference = (3 + 2 + 1 + 4) – (5 + 7 + 6) = 10 – 18 = 8
2471865 is divisible by 11.
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
