Question
The denominator of a rational number is 4 more than its
numerator. If the numerator is increased by 5 and the denominator is decreased by 3, we obtain 3. The rational number isSolution
ATQ, Let the numerator of the number = b Denominator = b+4 The number is = (b/b+4) Now, [(b+5)/(b+4-3)] = 3 [(b+5)/(b+1)] = 3 b+5 = 3b+3 2b = 2 b = 1 ∴ The required fraction =[(b)/(b+4)] = 1/5
What will come in the place of question mark (?) in the given expression?
(? ÷ 16) = (20 ÷ ?) X 20(286 ÷ 11 + 14) × 5 = 40 + 25% of ?
What will come in the place of question mark (?) in the given expression?
(70 × 8 ÷ 10) × 5 = ?
- What will come in place of (?), in the given expression.
(12% of 250) + (30% of 400) = ? What will come in the place of question mark (?) in the given expression?
What will come in the place of question mark (?) in the given expression?
? = {1026 ÷ 54 + 17 × 13 – (384 ÷ 24)}Â
?% of (√196) × 24 + 344 = 428
1200 - 60 X 6 + 30 = 30 X 20 + ?
400 % of 20 + 65 % of 620 - 92 × 5 = ?
58% of 3300 - ?% of 2900 = 1740
