STRIKE rate of Q = (Total runs/Total balls) × 100

⇒ 98 = (Total runs/1050) × 100

⇒ Total runs = (98 × 1050)/100

⇒ Total Runs = 1029

Total match PLAYED by Q = 21

AVERAGE = Total runs/Total match = 1029/21 = 49 runs

Let us assume total runs score by P = x

Average = x/15

Strike rate = (x/1000) × 100

Strike rate of player P = Strike rate of player R - 10% of strike rate of player R

⇒ 121 - (0.10 × 121)

⇒ 121 - 12.1

⇒ Strike rate of P = 108.9

Putting the value in strike rate equation;

⇒ 108.9 = (x/1000) × 100

⇒ x = (108.9 × 1000)/100

⇒ x = 1089

Average = 1089/15

Required RATIO = Average of player Q : Average of player P

⇒ 49 : 1089/15

⇒ 49 : 363/5

⇒ 245 : 363

∴ Required answer = 245 : 363
