Corrent answer is: 59 years Explanation: Let the present age of Ram. Rohan and Raj be 3x, 4x and 5x years respectively. $3x+4x+5x=3\times 28$ $=12x=84⟹x=\frac{84}{12}=7$ Sum of the age of Ram and Rohan after 5 years $=3x+4x+10=7x+10$ $=7\times 7+10=\text{59 years}$ Nithin ? answered undefined All Comments
