Answer 1

☞Question.

Rohit sold a bat for ₹ 1400 at a gain of 12%.for how much did he purchase it?

☞Solution.

s.p = $\sf\red{1400rs}$

gain = $\sf\red{ 12%}$

so,

c.p = $\sf\green{ s.p×100/ 100- loss}$

➝ $\sf\green{ 1400 × 100 / 88}$

➝$\sf\green{ 1590.90rs}$

$\sf\red{C.P\: formula-:}$

c.p = $\sf\green{s.p + loss}$

c.p = $\sf\green{ s.p - profit}$

c.p = $\sf\green{s.p ×100/100+profit}$

Answer 2

S.P. = ₹ 1400, Gain % = 12%.

∴ C.P. = {100/(100 + Gain%) × S.P.}

= ₹ {100/(100 + 12) × 1400}

= ₹ ( 100/112 × 1400)

= ₹ 1250

Hence, Rohit purchased the bat for ₹ 1250
