Question

( S P=₹ 240 )
Loss ( %=10 % )
( frac{c-5 p}{c p} times 100=10 )
( frac{c p-240}{c p}=0 cdot 1 )
( c p-240=0.1 c p )
( 0.9 c p=240 )
[
begin{aligned} c p &=frac{2400^{800}}{93}=frac{800}{9} R b end{aligned}
]
New spli with profit of ( 20 % )
( P %=frac{8 p-c p}{c p} times 100 )
( begin{aligned} P % &=20=frac{8 p^{prime}-800 / 3}{800 / 3} times 100 & 20=frac{38 p^{prime}-800}{8} & 38 p^{prime}=160+800 &left.frac{38 p^{prime}=960}{mid s p^{prime}=₹ 320}right|_{1 /} text { option }-(4) end{aligned} )
