The bar graph given below shows the number of books sold by two shopkeepers S1 and S2 in 5 months.
J1 = The total number of books sold by S1 and S2 in all 5 months.
J2 = The difference between the total number of books sold by S1 in all 5 months and the total number of books sold by S2 in all 5 months.
What is the value of (J1 + J2)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 260
(J1 + J2) = S1 + S2 + S1 - S2 = 2 S1
= 2 ( 50 + 40 + 20 + 15 + 5 ) = 260
