Question

7. Find CP if SP = rs.1800 and Loss % = 25%.
8. Find CP if SP = rs.2100 and Profit = 10%​

Answer 1

7. The value of CP = ₹ 2400

8. The value of CP = ₹ 1909.09

Step-by-step explanation:

7. Given,

SP = ₹ 1800 and loss % = 25 %

To find, the value of CP = ?

We know that,

CP = $\dfrac{100}{100-Loss Percent} \times SP$

= ₹ $\dfrac{100}{100-25} \times 1800$

= ₹ $\dfrac{100}{75} \times 1800$

= ₹ 100 × 24

= ₹ 2400

Thus, the value of CP = ₹ 2400

8. Given,

SP = ₹ 2100 and profit % = 10 %

To find, the value of CP = ?

We know that,

CP = $\dfrac{100}{100+Gain Percent} \times SP$

= ₹ $\dfrac{100}{100+10} \times 2100$

= ₹ $\dfrac{10}{11} \times 2100$

= ₹ 1909.09

Thus, the value of CP = ₹ 1909.09
