Jacob’s monthly income is $960 and him savings is $320. Find savings to expenses ratio.

Savings to expenses ratio is 1:2

Solution

Jacob's Income = $960

Savings = $320

Expenses = 960 - 320 = 640

∴ savings to expenses ratio = 320:640 = 1:2

Savings = $320

Expenses = 960 - 320 = 640

∴ savings to expenses ratio = 320:640 = 1:2

2

Out of 132 students in a class, 60 are boys. Find boys to girls ratio.

Boys to girls ratio is 5:6

Solution

Total Number of students = 132

boys = 60

girls = 132 - 60 = 72

∴ Boys to girls ratio = 60:72 = 5:6

boys = 60

girls = 132 - 60 = 72

∴ Boys to girls ratio = 60:72 = 5:6

3

Length and breadth of a rectangular field are 80 feet and 24 feet respectively. Find the ratio of length to breadth of the field.

Length to breadth ratio is 10:3

Solution

Length of a rectangular field = 80

breadth of a rectangular field = 24

∴ Length to breadth ratio = 80:24 = 10:3

breadth of a rectangular field = 24

∴ Length to breadth ratio = 80:24 = 10:3

4

Out of 117 students in a class, 9 prefer football, 63 prefer baseball and remaining like tennis. Find the ratio of number of students who prefer football to number of students who prefer tennis.

Number of students who prefer football to number of students who prefer tennis ratio is 1:5

Solution

Total Number of students = 117

Number of students prefer football = 9

Number of students prefer baseball = 63

Number of students prefer tennis =117 - (9 + 63) = 45

∴ Number of students who prefer football to number of students who prefer tennis ratio = 9:45 = 1:5

Number of students prefer football = 9

Number of students prefer baseball = 63

Number of students prefer tennis =117 - (9 + 63) = 45

∴ Number of students who prefer football to number of students who prefer tennis ratio = 9:45 = 1:5

5

∴ Number of teachers to number of students ratio = 90:2655 = 2:59

Total Number of students = 2655

∴ Number of teachers to number of students ratio = 90:2655 = 2:59

Self employed = 6200 - 3920 = 2280

∴ Government employees to self-employed ratio = 3920:2280 = 98:57

Number of Government employees = $3920

Self employed = 6200 - 3920 = 2280

∴ Government employees to self-employed ratio = 3920:2280 = 98:57
