Question
6 years ago from now, ratio of ages of ‘R’ and
‘L’ was 5:7, respectively. If ‘L’ is 6 years elder to ‘R’, then what will be the age of ‘L’, 10 years hence from now?Solution
6 years ago from now, let ages of ‘R’ and ‘L’ be ‘5x’ years and ‘7x’ years, respectively. So, 7x – 5x = 6 Or, 2x = 6 Or, x = 3 Present age of ‘L’ = 7x + 6 = 7 × 3 + 6 = 27 years Age of ‘L’, ten years hence from now = 27 + 10 = 37 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
