Answer:
The number is 240 (a)
Explanation:
Let the number be x
So,
(one half) of (one third) of (one quarter) of (one fifth) of x = 2
1/2 of 1/3 of 1/4 of 1/5 of x = 2
here 'of' means multiplied by...
1/2 * 1/3 * 1/4 * 1/5 * x = 2
multiplying the fractions we get,
1/(2*3*4*5) x = 2
1/120 x = 2
bring 1/120 to the right side of the equation, it becomes 120/1
x= 2*120/1
= 2*120
= 240
