Here are three numbers whose values are between 0.33 and 0.34 :
0.3300001
0.335
0.3399999
Let 70% of X = 98
70%.x = 98
(70/100).x = 98
0,7x = 98
x = 98/0,7
x = 140
Then, 90%x = 90%.140
= 0,9.(140)
= 126
The answer to this question is Letter D)
I hope this has helped.
5/12 is the answer just do 15 and then add 15 + 21 to get 36 and then you reduce 15/36 and get 5/12
