Question

In the last three months Mr. sharma lost 11/2 kg, gained 9/4 kg and then lost 15/4 kg. If he now weighs 95 kg, how much Did Mr. Sharma weigh to begin with?

Answer 1

Let the starting weight be x.
1 he lost 11/2 kg.
i.e.x-11/2=2x-11/2kg

Then he gained 9/4kg
i.e. (2x-11)/2 +9/4
=(4x-22)+9/4
=4x-13/4

Again he lost 15/4kg
i.e. 4x-13/4-15/4
=4x-13-15/4
=4x-28/4
Now according to ques.
4x-28/4=95kg
4x=95+28/4
4x=380+28/4
4x=408/4
X=102×4
×=408 kg.

Answer 2

Let x be the weight of Mr. Sharma in beginning.

According to given details,

x−$\frac{11}{2}$ + $\frac{9}{4}$ −$\frac{15}{4}$ =95

⇒x=95+$\frac{11}{2}$+ $\frac{15}{4}$− $\frac{9}{4}$

=95+7=102 kg.

So, the answer is 102 kg.
