at a fruit stall 2/7 of the total number of fruits are oranges,5/9 are pears and 3/8 of the remainbing are apples.if there are 210 apples,find the total number of fruits at the stall?

Solution:-Let total number of fruits=x

Remaining number of fruits= x-2x/7-5x/9= (63-18-35)x/63= 10x/63.

3/8 of 10x/63=210

So, 30x/504=210

x=(210*504)/30=3528

Total number of fruit=3528
