Study the following table and answer the question:-

Number of cars sold by dealers P, Q, R, S and T during first six months of 2022.

In July 2022, if sales of car by dealer Q increases by double the number as in June 2022 over its previous month, then what is %age increase in sale in July 2022 comparatively June 2022 (approx.)?

55%

Increase in sale by Q in June over May = (620 - 450) = 170

double the no. = 340
