Answer 1

$\huge\mathfrak{\underline{\underline{Answer:-}}}$

Munna subtracts thrice the number of notebooks he has from 50, he finds the

result to be 8.

Let the number of notebooks be x.

Total number of books :- 50

Result :- 8

According to problem ,

50 - 3x = 8

or -3x = 8 - 50

or -3x = -42

or x = -42/-3

or x = 14

Answer :- 14

Answer 2

$\bold{\underline{\underline{Answer:}}}$

Number of notebooks = 14

$\bold{\underline{\underline{Step\:-\:by\:-\:step\:explanation:}}}$

GIVEN :-

• Munna subtracts thrice the number of notebooks he has from 50
• On subtracting,he finds the
• result to be 8.

TO FIND :-

• Number of notebooks

SOLUTION :-

Let the number of notebooks be x

Munna has a total of 50 notebooks

$\bold{\underline{\underline{As\:per\:the\:condition:}}}$

• Munna subtracts thrice the number of notebooks he has from 50

Thrice the number of notebooks will be 3x

Solving the question further,

$\implies$ $\bold{50\:-\:3x\:=\:8}$

$\implies$ $\bold{-3x\:=\:8\:-\:50}$

$\implies$ $\bold{-3x\:=\:-42}$

$\implies$ $\bold{x\:=\:\frac{-42}{-3}}$

$\implies$ $\bold{x\:=\:14}$
