Avg. distance covered by a wheel= 4*621/6=414

2). Answer: d)

Explanation:

Cost price of 20 books =x

Cost price of 10 books will be x/2

Selling price of 10 books=x

Shortcut:

No.of books amount gained as profit on selling 10 books=10/10*100%=100%

3).

Answer: a

Explanation:

Let the total no. of balls be y

No. of balls with Aswini=30

No. of balls with Aditi = y/5+20+15=y/5+35

No. of balls with Akshara =7/12(y/5+35)

30+y/5+35+7/12(y/5+35) =y

y = 125

No. of balls with Aditi = 125/5+35=60

No. of balls with Aditi at the end=60-15=45
