Answer 1

$\bold{ \red{CLARIFICATION:}}$

GIVEN :

$\mathtt {Total \: value \: of \: 50 \: paise \: coins = 0.5 \times x}$

$\mathtt {Total \: value \: of \: one \: rupee \: coins = 1 \times 2x}$

$\mathtt{Total \: value \: of \:two \: rupee \:coins = 2 \times 5x}$

$\mathtt{Total \: value \: of \: these \: coins =50}$

TO FIND:

Value of x= ?

SOLUTION:

Let the total value of given coins be R

$\mathtt{R=0.5×x+1×2x+2×5x=50}$

$\implies \mathtt{0.5x+2x+10x=50}$

$\implies \mathtt {12.5x=50}$

$\implies \mathtt {x = \frac{50}{12.5} }$

$\implies \mathtt {x = 4}$

Therefore the value of x is 4
