The bar graph given below shows the number of shoes in 8 shops. R = Difference between the total number of shoes in S5 & S6 and the total number of shoes in S1 & S8. T = Average number of shoes in S2, S4 and S5. What is the value of R + T? Correct Answer 340

Given:

The number of shoes in 8 shops

S1 = 780, S2 = 340, S3 = 460, S4 = 720

S5 = 350, S6 = 700, S7 = 900, S8 = 400

Formula used:

Average = Sum of observations/Number of observations

Calculations:

R =

R =

R =

R = -130

Similarly,

T = (S2 + S4 + S5) / 3

T = (340 + 720 + 350) / 3

T = 1410 / 3

T = 470

The value of (R + T) = (-130 + 470) = 340

Hence, correct answer is 340.
