Answer:
(2.9)+(2.7)=32 I think at is the answer
Answer:
10=40
50=30
Step-by-step explanation:
Suppose the number of 10 paise coins =x
∴ the number of 50 paise coins =70−x
Now, value of 10 paise coins = Rs.
10
x and value of 50 paise coins = Rs.
2
70−x
Total value of coins =
10
x
+ 2
70−x
∴ 10
x + 2
70−x =19
Multiplying both sides by 10, (LCM of 10,2=10), we get
x+5(70−x)=19×10
x+350−5x=190
−4x=−160
−4
−4x = −4
−160
∴x=40
∴ number of 10 paise coins =40
Number of 50 paise coins =70−40=30.
