Question
A girl spent 32% of her monthly income on clothing. Of
the remaining, she spent on travel and food in the ratio of 5:3. If the difference of the income spent on travel and food is Rs.1224, then find her monthly income.Solution
Let her income be 100%. Remaining income = (100 - 32)% = 68% Let the money spent on travel and food be Rs. 5x and Rs. 3x respectively. Now, according to question, => 5x – 3x = 1224 => x = 612 Total money spent on travel and food together = 8x = 4896 => 68% --- 4896 => 100% ----- 7200 Therefore her income is Rs. 7200.
What will come in the place of question mark (?) in the given expression?
(18 × 8 + 24) × 4 = ?
215 + 378 – 23 + 15 - 27 = ? + 3² + 16²
Simplify the following expressions and choose the correct option.
 (96 ÷ 8 + 72 ÷ 9) * 3
82% of 400 + √(?) = 130% of 600 - 85% of 400

13 X √? + 256 ÷ 4 = 30% of 900 - 50

612 + 1250 - 728 = ? × 63
- What will come in place of the question mark (?) in the following questions?
75% of 240 + 30 = ? 16 × 14 + 30 × 21 = 14 × ?
