The pie chart above represents 400 fruits on display n a grocery store. How many apples are in the store

Sectorial angle of apple
100 + 100 + 115 + x = 30${}^{\circ }$
315 + x = 360
x = 360 - 315
x = 45${}^{\circ }$
360${}^{\circ }$ represents 400
1${}^{\circ }$ represents 400 / 360
45${}^{\circ }$ represents (400/360) x (45/1)
= 50 apples
