Question
A shirt is marked 40% above the cost price and sold
after a discount of Rs.108 at Rs.452. Find the cost price of the shirt.Solution
Let the cost price of the shirt be Rs.x. Marked price = Rs.1.4x According to question, => 1.4x – 108 = 452 => 1.4x = 560 => x = Rs.400
242 + 80% of 1620 = ? × 16 – 35% of 800
I. 8x² - 74x + 165 = 0
II. 15y² - 38y + 24 = 0
323 × 15 + (?)² = 4989
- Simplify the following expression:
(48% of 800 × 3) ÷ 6 + 440 ÷ √25 - 14² (1/3) + (2/5) + (3/4) + (11/10) = 3 – (?/12)

What will come in the place of question mark (?) in the given expression?
45% of (√6400 × 5) = ? + 111
What will come in the place of question mark (?) in the given expression?
60% of 280 + 40% of 120 = ? ÷ 4
What will come in the place of question mark (?) in the given expression?
?% of 192 = 242 – 48 × 11
The value of 5³ × 5⁴ × 5² = ?
