Question

An amount of 2440 consists of #100 and #10,the number of 100 is 6times as much as 10,find the number of100 and 10

Answer 1

number of hundreds --- h
number of tens ------ t

h = 6t

100h + 10t = 2440
100h + 60t = 2440
160t = 2440
t = 15.25 ----> not possible

Your data is inconsistent.

Answer 2

Let number of #10 be T,100 is 6times as many as 10=6T,So 100(6T)+10(T)=2440,610(T)=2440,t=4 since T=4,6T=24,

Answer 6

number of #100 notes --- h
number of #10 notes ------ t

100h + 10t = 2440 ...(1)
h = 6t ....(2)

Sub. Eqn. (2) into (1)

100h + 10t = 2440
100(6t) + 10t = 2440
600t + 10t = 2440
610t = 2440
t = 2440/610
t = 4

Put t= 4 into eqn. (2)

h = 6(4)
h = 24
Therefore, we have 24 #100 notes and 4 #10 notes.
