Question
This question is based on the following 3-digit
numbers: 543, 769, 552, 342, 245 (Example: 697 – First digit = 6, second digit = 9, and third digit = 7) If in each of the numbers, 1 is added to the first digit of every number, in how many numbers will the first digit be exactly divisible by the third digit of the same number?Solution
ATQ,
Add 1 to the first digit of each number and check if it's divisible by the third digit: 543 → 6 ÷ 3 ✅ 769 → 8 ÷ 9 ❌ 552 → 6 ÷ 2 ✅ 342 → 4 ÷ 2 ✅ 245 → 3 ÷ 5 ❌ ✅ Total valid numbers = 3

What will come in the place of question mark (?) in the given expression?
(5/8) × 1600 + (2400 ÷ 25) = ?
- What will be come in place of (?) in the given expressions.
45% of 640 + 35% of 320 = ? 5 × 14 + 100 ÷ 4 = 62 + ?
690 ÷ (75% of 460) = ? ÷ (50% of 160)
115 ÷ 23 + 12 × 6 = ? + 16 - 35
Simplify the following expressions and choose the correct option.
(45% of 640) ÷ 8 + (3/4 of 96) = ?
15% of 360 × 20% of ? = 324
- What will come in the place of question mark (?) in the given expression?
(120 - ?) ÷ 2 + 35 = 86 - 11 8 × 9 + ? – 6 × 11 = 12 × 8
[1.45 X 1.45 X 1.45 + 0.55 X 0.55 X 0.55 + 4.785] = ?
