How many Samosas?

Algebra Level 2

Rohan , Mohan , Sohan , and Tohan are sons of Mrs. Tihari. One day she made them some samosas and went for work. She had put a sign next to the samosas that said , " All of you take ¼ of the samosas ". Rohan came home first and saw the sign and obeyed it. Mohan came home next but assumed that he was the first brother home. He saw the sign but he felt a little extra hungry , so he took one extra. Next , Sohan came home , and saw the sign but greedily took 2 extra. Finally , Tohan came home and and took all the samosas left. Later , when their mother came home , they learned that they had all eaten the same amount of samosas!

Question : How many samosas did Mrs. Tihari make?

Note : Each of the brothers went out after eating the samosas , so they couldn't have meet each other to know the exact amount of samosas they were supposed to take.


The answer is 16.

  • Let the number of Samosas made by Mrs. Tihari equal x x .
  • Then, Rohan ate 1 4 x \dfrac{1}{4}x
  • Mohan ate 1 4 \dfrac{1}{4} th of what was left ( 3 4 x ) \big(\dfrac{3}{4}x\big) + 1

Rohan Samosas = Mohan Samosas 1 4 x = 1 4 ( 3 4 x ) + 1 4 x = 3 x + 16 After × 16 x = 16 \begin{aligned} \text{Rohan}_{\text{Samosas}} &= \text{Mohan}_{\text{Samosas}} \\ \\ \dfrac{1}{4}x &= \dfrac{1}{4} \big(\dfrac{3}{4}x\big) + 1 \\ 4x &= 3x + 16 \quad \color{#3D99F6} \text{After }\times 16 \\ x &= \boxed{16} \end{aligned}

Let's represent the amount of samosas in the beginning as s.

Amount of samosas Rohan took = ¼ s Amount of samosas Mohan took =( (¾•¼) s) + 1

Therefore , ¼ s = (3/16 s ) + 1

¼ s + 1 = 3/16 s

1 = (1/4 - 3/16 )s

1 = 1/16 s

s = 16
