## DAV Class 5 Maths Ch 12 Worksheet 5 Solutions

Question 1.

Solve the following questions:

(a) Rohan gets 38 out of 50 in his monthly test of Mathematics. Express his marks in percentage.

Solution:

Maximum marks = 50

Marks scored = 38

% of marks = (\(\frac{38}{50}\) × 100)% = 76%

His mark in percentage is 76%.

(b) In a class of 45 students, 60% are boys. Find the number of boys in the category.

Solution:

Total students = 45

% of boys = 60%

No. of boys in the class = \(\frac{60}{100}\) × 45 = 27

Number of boys in the class is 27.

(c) In an orchard of 400 trees, 35% are mango trees. 42% were apple trees and the rest were grape vines. How many grape vines are there?

Solution:

Total trees = 400

% of mango trees = 35%

% of apple trees = 42%

% of grape vines = (100 – 35 + 42)%

= (100 – 77)%

= 23%

Number of grape vines = 23% of 400

= \(\frac{23}{100}\) × 400

= 92

92 grape vines are there.

(d) Mr Mahesh earns ₹ 7,200 per month. He spends 33\(\frac{1}{3}\)% on food. Find the amount spent on food.

Solution:

Total earnings = ₹ 7,200 per month

Spends on food = 33\(\frac{1}{3}\)%

Amount spends on food = 33\(\frac{1}{3}\)% of ₹ 7,200

= \(\frac{100}{300}\) × 7,200

= ₹ 2,400

₹ 2,400 is spent on food.

(e) Anil got 440 marks out of 800 and Gopi got 486 marks out of 900 in an examination. Who scored better?

Solution:

Maximum marks = 800

Anil scored = 440

% of marks = (\(\frac{440}{800}\) × 100)% = 55%

Maximum marks = 900

Gopi scored = 486

% of marks = (\(\frac{486}{900}\) × 100)% = 54%

Anil scored better.
