Question
The combined current ages of Ram and Shyam add up to 56
years. Four years from now, the age ratio of Ram to Shyam will be 3:5. Determine the age difference between Ram and Shyam.Solution
4 years hence from now, let the ages of Ram and Shyam be '3y' years and '5y' years, respectively So, present ages of Ram and Shyam is (3y - 4) years and (5y - 4) years, respectively We have, (3y - 4) + (5y - 4) = 56 So, 8y = 56 + 8 = 64 So, y = 64 ÷ 8 = 8 So, difference between ages of Ram and Shyam = 5y - 3y = 2y = 2 X 8 = 16 years
What value should come in the place of (?) in the following questions?
70% of 240 + 75% of ? = 45 * 55 ÷ 5
(33 + 6.25% of 4096) = ? + 2 × 119
What will come in the place of question mark (?) in the given expression?
65% of 900 - 45% of 600 = ? X 3
212.3 × 4414.7 × 4623.4 × 4845.85 = 462?
18/2 of 3/9 of 2/6 of 69690 = ?
Simplify the following questions and choose the correct option.
(84 × 3) ÷ 7 + (64 ÷ 8 × 5) − 19 = ?
7/11 × 1034 + 1(4/7) × 2401 = 1230 +?
(1520 - 1350) ÷ (550 – 500) = ?
What is the value of 7/9-11/12+12/16-1/8?
85% of 620 + ? % of 1082 = 4855
