Question
In an exam, Sunil scored 45% marks and failed by 18
marks while Rina scored 90% marks and scored 72 marks more than the passing marks. Find out the passing marks in the exam.Solution
ATQ, Let the maximum marks of the exam be '100x' ATQ: Passing marks of the exam = 100x X 0.45 + 18 = 100x X 0.9 - 72 Or, 45x + 18 = 90x - 72 Or, 45x = 90 Or, x = (90/45) = 2 Therefore, the maximum marks of the exam = 100x = 100x X 2 = 200 Required passing marks = 200 X 0.45 + 18 = 90 + 18 = 108
What will come in the place of question mark (?) in the given expression?
?% of 192 = 242 – 48 × 11
What will come in the place of question mark (?) in the given expression?
45% of (√6400 × 5) = ? + 111

- What will come in place of (?), in the given expression.
√2025 + 35% of 400 = ? 15% of 695 – 12.5% of 250 =? – 1200
7, 8, 12, 21, 37, ?
22 – 15 + 20 × 18 ÷ 6 – 34 = ?
[4(1/3) + 4(1/4)] × 24 – 62 = ?2
[(1245 ÷ 9) ÷ 12] × 540 = ?2 – 175
Simplify the following expression
