Question

Write a word problem or context that models the following equations. Try to make your real-life.

½ x + 6 = 81

(2t + 5) - t = 26

2(L) + 3(4L) = 990.50

Answer 1

First question :

The number of boys in a school is 6 more than 1/2 times of number of girls, if the number of boys is 81 then how many girls are there ?

Solution : Let x be the number of girls,

As per the above statement,

`(1)/(2)x+6=81`

Second question :

Two pipes filled two tanks of same size, if the difference in time taken by both pipes is 26 minute, if one takes 5 more than 2 times of the time taken by other, what is the time taken by smaller pipe,

Solution : If t be the time taken ( in minutes ) by smaller pipe,

So, the time taken by larger pipe = 2t + 5

As per the above statement,

`(2t+5)-t=26`

Third question :

The length of a pole is 4 times of the other pole if the sum of 2 times of small pole and 3 times of larger pole is equal to 990.50 inches what is the length of smaller pole,

Solution : If L be the length of smaller pole,

So, the length of larger pole = 4L,

As per the above statement,

2(L) + 3(4L) = 990.50
