= $\text"55x"/24$ = 55 (or), x = Rs.24
Question : 4
A boy was asked to find $3/5$ of a fraction. Instead, he divided the fraction by $3/5$ and got an answer which exceeded the correct answer by $32/75$ . The correct answer is
a) $2/15$
b) $2/25$
c) $6/25$
d) $3/25$
Answer »Answer: (c)
Let the fraction be x,
According to the question,
$x/{3/5}$ - $x × 3/5 = 32/75$
${5x}/3$ - ${3x}/5 = 32/75$
${25x – 9x}/15 = 32/75$
${16x}/15 = 32/75$
$x = 32/75 × 15/16 = 2/5$
Correct answer = $2/5 × 3/5 = 6/25$

b) $4/5$
c) $3/5$
d) $2/3$
Answer »Answer: (c)
Let the fraction = x
According to the question;
$6/7$ of x = $x/{6/7} - 13/70$
= $\text"6x"/7 = \text"7x"/6 - 13/70$
= $\text"7x"/6 - \text"6x"/7 = 13/70$
= $\text"49x - 36x"/42 = 13/70$
= $\text"13x"/42 = 13/70$
x = ${13×42}/{70×13} = 3/5$
