The following pie chart shows the amount of loan given by each of seven different banks as a percentage of the total loan given by these 7 banks taken together.
What will be the angle made by the sector B2?
Total loan given by all the seven banks taken together = (12+17+14+18+21+10+8)%
$$100\%=360^{\circ\ }$$
$$1\%=3.6^{\circ\ }$$
So $$17\%=17\times3.6^{\circ\ }$$
Angle made by the sector B2 = $$61.2^{\circ\ }$$
