Sonu has 5 dozen toffies. He gave 1/3 of these to Amit. 2/5 of these to Anil and 1/12 of these to Hamid. The number of toffees left with Sonu is :
(a) 9
(b) 11
(c) 5
(d) 7
Answer: (b) 11
Solution:-
Sonu has 5 dozen toffies,
The number of toffies in 5 dozen = 12 x 5
= 60
He gave 1/3 of these to Amit = 60/3
= 20,
He gave 2/5 of these to Anil = 60 x 2/5
= 24,
He gave 1/12 of these to Hamid = 60/12
= 5,
The number of toffies left with Sonu = 60 – (20 + 24 + 5)
= 60 – 49
= 11
Hence, the correct answer is option (b) 11.
