Answer:
He scored 176 on Friday.
Explanation:
Given,
The score on Monday = 11
Also, the score is doubled his score each day thereafter.
Therefore, the score on Tuesday = 2 × the score on Monday = 2 × 11 = 22,
Similarly,
The score on Wednesday = 2 × 22 = 44,
The score on Thursday = 2 × 44 = 88
The score on Friday = 2 × 88 = 176
Hence, he scored 176 on Friday.
