HELLO!!

5)Answer:(b)₹2880

Explanation:

$sp = \frac{(100 + profit\%)}{100} \times cp$

where sp = selling price,cp = cost price.

$sp = \frac{(100 + 20)}{100} \times 2400$

$sp = \frac{120}{100} \times 2400$

$sp = 120 \times 24$

$sp = 2880$

SELLING PRICE = ₹2880

6)Answer:(c)₹3600

EXPLANATION:

$cp = \frac{100}{100 - loss\% } \times sp$

where cp= cost price,sp =selling price.

$cp = \frac{100}{100 - 10} \times 3240$

$cp = \frac{100}{90} \times 3240$

$cp = \frac{10}{9} \times 3240$

$cp = 10 \times 360$

$cp = 3600$
