Answer 1

SOLUTION

GIVEN

A batsman scores some runs in the 51 st inning which increases his average from 51.1 to 60.

TO DETERMINE

The number of runs scored by the batsman in the 51 st innings.

EVALUATION

Here it is given that a batsman scores some runs in the 51 st inning which increases his average from 51.1 to 60

So average in 50 innings = 51.1

Total number runs in 50 innings

= 50 × 51.1

= 2555

Again the average in 51 innings = 60

Total number runs in 51 innings

= 51 × 60

= 3060

Hence number of runs scored by the batsman in the 51 st innings

= 3060 - 2555

= 505

प्रश्न :- एक बल्लेबाज 51वी पारी में कुछ रन बनाता है जिससे उसका औसत 51.1 से बढ़कर 60 हो जाता है बल्लेबाज द्वारा 51वी पारी में बनाई गई रण की संख्या ज्ञात करे . ?

उतर :-

माना बल्लेबाज 51वी पारी में x रन बनाता है l

तब,

→ पहली 50 पारी का औसत = 51.1

→ पहली 50 पारी में कुल रन = 51.1 * 50 = 2555

अब,

→ 51 पारी का औसत = 60

→ 51 पारी में कुल रन = 51 * 60 = 3060

अत,

→ 2555 + x = 3060

→ x = 3060 - 2555

→ x = 505 (Ans.)
