The following graph shows the data of the collection of interest on loans (in crore €) by six branches B1, B2, B3, B4, BS and B6 of a bank during the years mentioned.

Based on the information, from the year 2016 to 2017, the highest rate of collection is for the branch:

B6

Lets solve one by one for each option.

1. B4

Increase in rate of collection = \(\frac{40-34 }{34}\) × 100

= \(\frac{6}{34}\) × 100

= 17.6%

2. B1

Increase in rate of collection = \(\frac{52-43 }{43}\) × 100

= \(\frac{9}{43}\) × 100

= 20.9%

3. B3

Increase in rate of collection = \(\frac{35-28 }{28}\) × 100

= \(\frac{7}{28}\) × 100

= 25%

4. B6

Increase in rate of collection = \(\frac{38-25 }{25}\) × 100

= \(\frac{13}{25}\) × 100

= 52%

So ,  the highest rate of collection is for the branch B6

Ans :- B6
