Question 10 Percentage Exercise 12.2

A cricketer hit 120 runs in 150 balls during a test match. 20% of the runs came

in 6’s, 30% in 4’s, 25% in 2’s and the rest in 1’s. How many runs did he score in

(i)6’s

(ii)4’s

(iii)2’s

(iv)singles

What % of his shots were scoring ones?

Answer:

The given details are,

Total number of runs scored by cricketer = 120

(i)20% of Runs scored in 6’s = (20/100) × 120 = 24 runs

(ii)30% of Runs scored in 4’s = (30/100) × 120 = 36 runs

(iii)25% of Runs scored in 2’s = (25/100) × 120 = 30 runs

(iv)Runs scored in singles = 120 – (24+36+30)

= 120 – 90 = 30 runs

Percentage of shots scoring ones = (Runs came in singles/Total runs scored) × 100

= (30/120) × 100

= 25%
