Question 4 Comparing Quantities - Exercise

In a scout camp, 40% of the scouts were from Gujarat State and 20% of these were from Ahmedabad. The percentage of scouts in the camp from Ahmedabad is:

(a) 25 (b) 32.5 (c) 8 (d) 50

Answer:

(c) 8

From the question, it is given that,

In a scout camp, 40% of the scouts were from Gujarat State

So, let us assume the number of scout in the camp be 100

Then, scouts from Gujarat = 40% of 100

= (40/100) × 100

= 4000/100

= 40

Now, 20% of scouts were from Ahmedabad = 20% of 40

= (20 /100) × 40

= 800/100

= 8

Therefore, the percentage of scouts in the camp from Ahmedabad is 8.
