To Find the Principal Amount (Cost Price) in Installments when Markup, R, and T are Known (WP No.2 Markup)

The markup on a principal amount is Rs. 820 for 6 months at the rate of 12.5% per annum. Calculate the principal.

Given:

Markup = Rs. 820
Markup rate (R) = 12.5 % per annum
Time period (T) = 6 months = `{\frac{6}{12}}`years = `{\frac{1}{2}}`years

To Find:

Principal (P) = ?




Solution:

Using the formula,




.........Eqn (1)

From Eqn (1) formula for Principal (P) can be wriiten as using Basic Mathematics Rules.

Principal (P) = `\frac{Rs. 820\times100}{12.5\times(\frac1{2})}`

Markup =Rs. 13,120
