Explanation:

Given total number of cows = k

Now, 1st son share = k/2

2nd son share = k/4

3rd son share = k/5

4th son share = 9

(k) + (k/4) + (k/5) + 9 = k

=> k - (19k/20) = 9

=> (20k-19k)/20 = 9

=> k = 180.

Therefore, the company has 11 small cars.

A) 1124 | B) 1420 |

C) 1345 | D) 1250 |

Explanation:

Let initially 'X' ticket has been sold.

So now in 2nd week 20% increases, so

=> X x 120/100

In 3rd week 16% increases, so

=> X x (120/100) x (116/100)

In 4th week 20% decrease, so

=> X x (120/100) x (116/100) x (80/100) = 1392

X = 1250.
