$?$ 0.30 gm glycine is present in 100 gm protein

$∴$ 75 gm glycine is present in $\frac{100}{0.30} * 75 = \frac{10000}{30} * 75 = 25 * 1 0^{3} g / m o l$

The following table gives the career record in the One-Day Internationals of few of the Indian batsmen:

Name	Matches Played	Innings Played	Runs Scored	Average
Rohit	50	48	1800	40
Gill	50	50	2034	45.2
Virat	46	46	1679	36.5
Shreyas	44	44	1539	40.5
Hardik	40	38	1806	51.6
Rahul	42	40	1445	42.5

The average is calculated by dividing the total runs scored by the total number of matches in which the batman got out.

To reflect the performance of the players better, it was decided that the average would be calculated on the basis of the total matches played. Whose average will see the minimum change due to this?

Rohit – 1800840 = 45

Hence, not-out in 3 innings

Gill – 2034/45.2 = 45

Hence, not out in 0 inings

Virat – 1679/36.5= 46

Hence, not–out in 0 innings

Rahul – 1445/42.5 = 34

Hence, not-out in 6 innings

Therefore, option (d) is the correct answer
