CBSE NCERT Solutions for Class 6 Maths Chapter 12:

Question-1:

In a year, Seema earns 1, 50,000 and saves 50,000. Find the ratio of:
(a) Money that Seema earns to the money she saves.
(b) Money that she saves to the money she spends.

Solution:

a) Total earning = 1, 50,000 and saving= 50,000
Therefore, Money spent = ` 1, 50,000 - 50,000 = 1, 00,000
(a) Ratio of money earned to money saved = 150000/50000 = 3/1 = 3:1
(b) Ratio of money saved to money spend = 50000/100000 = ½ = 1:2

Question-2:

There are 102 teachers in a school of 33oo students. Find the ratio of the number of teachers to the number of students.

Solution:

Ratio of number of teachers to that of students= 102/3300 = 17/550 = 17:550

Question-3:

Out of 1800 students in a school, 750 opted basketball, 800 opted cricket and remaining opted table tennis. If a student can opt only one game, find the ratio of:

Solution:

Total number of students = 1800
Number of students opted basketball = 750
Number of students opted cricket = 800
Therefore, number of students opted tennis = 1800 – (750 + 800) = 250
(a) Ratio of students opted basketball to that of opted table tennis = 750/250 = 3/1 = 3:1
(b) Ratio of students opted cricket to students opted basketball = 800/750 = 16/15 = 16:15
(c) Ratio of students opted basketball to total no. of students = 750/1800 = 5/12 = 5:12

Question-4:

Cost of a dozen pens is 180 and cost of 8 ball pens is 56. Find the ratio of the cost of a pen to the cost of a ball pen.

Solution:

Cost of a dozen pens (12 pens) = 180
Cost of the pen = 180/12 = Rs 15
Cost of 8 ball pens = Rs 56
Therefore, cost of 1 ball pen = 56/8 = Rs 7
Ratio of cost of one pen to that of one pen = 15/7 = 15:7
