A) 26 B) 36 C) 46 D) 56

Answer 1

Answer:

there are 36 exercise books.

Step-by-step explanation:

let the total no. be x.

then , the no. of pencils =  10x

no. of pens =  2x

no. of exercise books = 3x

no. of pencils = 120

A.T.Q ,

10x = 120

x = 120/10

x = 12

no. of exercise books = 3x

                                     = 3×12

                                      =36

total no. of exercise books is 36.
