For a sum of ₹15,000 the rate of interest of 8.5% per annum simple interest, find the interest earned (in ₹) in 5 years 3 months.
A dealer sells his goods at 5% loss on cost price but uses \(12\tfrac{1}{2}\%\) less weight. Find his percentage of loss or gain.
\(\text{Gain } 7\tfrac{4}{7}\%\)
\(\text{Gain } 8\tfrac{4}{7}\%\)
\(\text{Loss } 8\tfrac{4}{7}\%\)
\(\text{Loss } 7\tfrac{8}{7}\%\)
Which of the following equations is correct?
\(\text{Gain \%} = \dfrac{CP}{(\text{gain} \times 100)}\)
\(\text{SP} = (100 - \text{gain\%}) \times \dfrac{CP}{100}\)
\(\text{SP} = (100 - \text{loss\%}) \times \dfrac{CP}{100}\)
\(\text{Loss} = SP - CP\)
