Answer 1

Answer:

Let the Ages of Hari and Harry be 5x and 7x years.

$</p><p>According \: to \: question, \frac{5x+4}{7x+4}=\frac{3}{4}7x+45x+4=43</p><p></p><p>\Rightarrow\ 4\left(5x+4\right)=3\left(7x+4\right)⇒ 4(5x+4)=3(7x+4)</p><p></p><p>\Rightarrow\ 20x+16=21x+12⇒ 20x+16=21x+12</p><p></p><p>\Rightarrow\ 20x-21x=12-16⇒ 20x−21x=12−16</p><p></p><p>\Rightarrow\ -x=-4⇒ −x=−4</p><p></p><p>\Rightarrow\ x=4⇒ x=4</p><p></p><p>$

Hence, the age of Hari = 5x= 4 x 5 = 20 years.

And the age of Harry = 7x = 7 x 4 = 28 years.
