The bar diagram given below shows the runs scored by five batsmen in a cricket match. J1 = Average runs scored by all five batsmen J2 = Difference between runs scored by E and D J3 = Difference between runs scored by C and B What is the value of (J3 – J2 + J1)?
The bar diagram given below shows the runs scored by five batsmen in a cricket match. J1 = Average runs scored by all five batsmen J2 = Difference between runs scored by E and D J3 = Difference between runs scored by C and B What is the value of (J3 – J2 + J1)? Correct Answer 71
Given:
J1 = Average runs scored by all five batsmen.
J2 = Difference between runs scored by E and D.
J3 = Difference between runs scored by C and B.
Formula used:
The average = (The of total items)/(The number of items)
Calculation:
J1 = Run scored by (A + B + C +D + E)/5
⇒ (95 + 105 + 135 + 75 + 145)/5
⇒ 555/5
⇒ 111
J2 = Difference between runs scored by E and D which is 145 - 75 = 70
J3 = Difference between runs scored by C and B which is 135 - 105 = 30
So the value of (J3 – J2 + J1)
⇒ 30 - 70 + 111
⇒ 71
∴ option D is correct.
