Answer :
let the no. be x
now, according to question, 30 % of x = 96
= 30/100 by x = 96
30x = 9600
thus, x = 320.
Thus, 30% of 320 is 96.
2) let the no. be y
now, according to question,
15 % of y = 63
= 15/100 x y = 63
15y = 6300
thus, y = 420.
thus, 63 is 15% of 420
now, according to question, 30 % of x = 96
= 30/100 by x = 96
30x = 9600
thus, x = 320.
Thus, 30% of 320 is 96.
2) let the no. be y
now, according to question,
15 % of y = 63
= 15/100 x y = 63
15y = 6300
thus, y = 420.
thus, 63 is 15% of 420
