Question

saurabh has 34 fifty paise and twenty five paise if the number of 25 paise coins be twice the mo of 50 paise coins how many of each kind does he have

Answer 1

50 paise coins = x
25 paise coins = 2x
She has Rs34 = 3400 paise
50*x+25(2x)=3400
50x+50x=3400
100x=3400
x=3400/100
x= 34 ---- 50 paise coins
25 paise coins ---- 34*2= 68
CHECK
68*25 + 34*50 = 340
