Question
A is 4 years older than B while C is 5 years younger
than B. The ratio of age of A, 7 years hence and age of B, 6 years ago is 3:2. What was age of C, 11 years ago?Solution
Let the present age of B be x years. A’s present age = (x + 4) years C’s present age = (x - 5) years According to question, => [(x + 4) + 7]/(x -6) = 3/2 => x = 40 C’s age, 11 years ago = (40 - 5) – 11 = 24 years
- Identify x such that x% of 540 plus {1080 ÷ x of 9} × 6 gives 162
360 × 9 ÷ 3 + 120 + 900 ÷ 5 = ?
2350 – 4830 + 9570 + 3350 – 1720 = ?
12.5% of 384 - 16.66% of 66 = √16 + √? + 22
What will come in the place of question mark (?) in the given expression?
? = 60% of 48% of (20 × 350) + 180
What will come in the place of question mark (?) in the given expression?
(555 + 385 - 535) ÷ 15 X ? = 36 X 30
Find the simplified value of the given expression:
What is the value of 7/9-11/12+12/16-1/8?
48 ÷ 6 × √25 + 13 × 8 = ?
What will come in the place of question mark (?) in the given expression?
(308 – 154) ÷ 11 = ? ÷ 15
