• A. Nill
• B. Rs. 1440
• C. Rs. 2500
• D. Rs. 1960
• E. Rs. 1850

Answer 1

The correct option is B

Rs. 1440

S.P in 1${}^{st}$ case = 60% of Rs.100000=Rs.60000.

S.P in 2${}^{nd}$case=96% of 64%of Rs.100000

=Rs.$\left(\frac{96}{100}\times \frac{64}{100}\times 100000\right)$=Rs.61440.

$\therefore$Difference = Rs. (61440-60000)=Rs.1440
