Option (a) is correct

Let his average score before playing the 17th match (ie till 16th match) was x

As we know,

Average = (Runs Scored )/(matches/Innings)

So, x = (Runs )/16 ⇒ Runs = 16x

After 17th match his runs wil be = 16x + 98

So new average

= (16x+98 )/17 = x + 2.5 16x + 98 = 17x + 42.5

x = 55.5

विकल्प (a) सही है।

बता दें कि 17वां मैच (यानी 16वां मैच) खेलने से पहले उनका औसत स्कोर x था

जैसा कि हम जानते हैं,

औसत = (Runs Scored )/(matches/Innings)

तो, x = (Runs )/16 ⇒ Runs = 16x

17वें मैच के बाद उसके रन = 16x + 98 होंगे

तो नया औसत

= (16x+98 )/17 = x + 2.5 16x + 98 = 17x + 42.5

x = 55.5
