If they're integers, that means they can't be fractions (such as 15/2 and 2).
So the only couples of integers that, when multiplied, result in 15 are:
1 and 15
5 and 3.
(there are no other possibilities as both 5 and 3 are not divisible further).
The smaller of the two sums (15+1; 5+3) is 5+3=8.
The least possible sum of a and b is 8.
There are 10 seats in ferris wheel of love.
One couple can fit in to one seat. That means 1 couple per seat.
Given, in each minute a seat passes by the entrance or exit stage. That means one couple can use the seat for one minute. That means 1 seat per minute.
The wheel starts functioning at 8 p.m for half an hour. In 1 hour there are 60 minutes. So half an hour means
= 30 minutes.
So we have got 1 couple per seat and 1 seat per minute. If we multiply them we will get 1 couple per minute.
We have got in 1 minute there is 1 couple.
So in 30 minutes there are
couples = 30 couples.
We have got the required answer here.
There are 30 couples who took a ride in the ferris wheel of love.
When : 36 ÷ n = 4
10) n = 9
Plug in 9 for n
36 ÷ 9 = 4
Correct / true
11) n = 6
Plug in 6 for n
36 ÷ 6 = 4
Incorrect / false
12) n = 5
Plug in 5 for n.
36 ÷ 5 = 4
Incorrect / false
