✪ Question ✪
Ages of Ravi and Hemant are in the ratio of 5:7. Four years later the ages are in ratio of 3:4. Find their ages solutions.
✪ To find ✪
Their ages.
✪ Solution ✪
Let Ravi's age be 5x and Hemant's age be 7x yrs.
According to condition,
(5x+4):(7x+4) :: 3:4
→(5x+4)/(7x+4) = 3/4
→ 4(5x+4) = 3(7x+4)
→ 20x+16 = 21x+12
→ 20x-21x = 12-16
→ -x = -4
→ x = 4
✪ Hence ✪
Ravi's age = 5x yrs = (5×4) yrs = 20 yrs.
Hemant's age = 7x yrs = (7×4) yrs = 28 yrs.
✪ Therefore ✪
Ravi and Hemant's ages are 20 years and 28 years respectively.
