A trader bought goats for N4000 each. He sold them for
N180,000 at a loss of 25%. How many goats did he buy?

Solution:

A trader bought goats for N 4000 each

He sold them for  N 180,000 at a loss of 25%

To find: Number of goats bought

From given,

Cost price of 1 goat = 4000

Cost price of "x" goats = 4000x

Selling price of "x" goats at loss of 25 % is:

180000 = 4000x - 25 % of 4000x

Divide both sides by 0.75

x = 60

Thus he bought 60 goats

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
