Answer 1

$\color {red}\huge\bold\star\underline\mathcal{Question:-}$

we have to Find CP for Hari ...

$\bold{\boxed{\huge{\boxed{\orange{\small{\boxed{\huge{\red{\bold{\:Answer}}}}}}}}}}$

we know that ,

$sp \: = \frac{cp \times (100 + gain)}{100}$

Prem sold it to sudhir at a gain of 10% ,

so,

sudhir SP = Prem CP

sudhir SP =>

$sp = \frac{(7500 \times 110)}{100}$

$sp = 8250$

so, Prem bought the transister for 8250.

Now he sold it to Hari at a gain of 15% .

so,

SP of Prem = CP of Hari .

again, using same formula we get,

$sp = \frac{8250 \times 115}{100} = 9487.5$

so,

The transistor cost Hari = $\large\red{\boxed{\sf </strong><strong>9</strong><strong>4</strong><strong>8</strong><strong>7</strong><strong>.</strong><strong>5</strong><strong>\</strong><strong>:</strong><strong>Rs</strong><strong>.</strong><strong>}}$
