Answer:
100 sweets
Step-by-step explanation:
Let initial number of sweet = x
Monday :
2/5 of x = 2x/5
Number left = x - 2x/5 = 3x/5
Tuesday :
2/5 of remaining = 2/5 * 3x/5 = 6x/25
Number left = 3x/5 - 6/25 = 9x/25
Wednesday :
2/3 of remaining = 2/3 * 9x/25 = 18x/75
Number left = 9x/25 - 18x/75 = 9x / 75
9x/75 corresponds to 12
9x/75 = 12
Cross multiply :
9x = 12 * 75
9x = 900
x = 900 / 9
x = 100 sweets
