Answer
Find out the how many notes of each denomination did she give .
To prove
Let us assume that x be the scalar multiplication of the Rs 50, Rs100,Rs500 curreny notes.
As given
Kamala gave Rs 1,50,000 to her friend.
She gave currency notes of denomination Rs. 50,Rs.100,Rs.500 in the ratio 4:3:5.
Rs50 currency note gave in the denomination = 4x
Rs100 currency note gave in the denomination = 3x
Rs500 currency note gave in the denomination = 5x
than the equation becomes
4x + 3x + 5x = 150000
12x = 150000
x = 12500
Thus
Rs50 currency note gave in the denomination = 4 × 12500
= 50000
Rs100 currency note gave in the denomination = 3 × 12500
= 37500
Rs500 currency note gave in the denomination = 5 × 12500
= 62500

It just is
Answer:
76 comic books
Step-by-step explanation:
First we must structure a formula in order to solve for the number of comic books that Michelle initially had. The formula for this problem would be:
x · \frac{1}{2}x + 18 = 56
In order to solve for x, the initial number of comic books Michelle had, you would need to subtract 18 from 56. You would then have 38. So:
x · \frac{1}{2}x = 38
Next, you'd need to get rid of the \frac{1}{2}. In order to do that, you would divide \frac{1}{2} by 38. Now, we should be left with:
x · x = 76
Now, we don't really need both x's. We can already conclude that x is equal to 76, since the following is true:
76 comic books - \frac{1}{2} (76) sold + 18 bought = 56 comic books left.
Therefore, your answer is 76 comic books.
Use cross multiplication a/b = c/d ad = bc
1/50 = 18/x
1x = 18(50)
x = 900 cm
