The actual price of the article was Rs. 1200.

Step-by-step explanation:

mp (marked price)

ap (actual price)

mp = 1380

$mp = ap + 15\%(ap)$

$1 380 = ap + \frac{15}{100} ap$

$1380 = \frac{100}{100} ap + \frac{15}{100} ap$

$1380 = \frac{115}{100} ap$

$1380 \div \frac{115}{100} = ap$

$1380 \times \frac{100}{115} = ap$

$\frac{138000}{115} = ap$

1200 = ap

$12\times (6+5)$

Step-by-step explanation:

We have been given a sum 72+60 . We are asked to rewrite this sum using distributive property and greatest common factor.

First of all, we will find greatest common factor of 72 and 60.

Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

We can see that the greatest common factor of 72 and 60 is 12.

We can rewrite our given sum as:

$12\times 6+12\times 5$

Upon factoring out 12, we will get:

$12\times (6+5)$

Therefore, our required expression is $12\times (6+5)$ .
