Question

A 45 gm tube of 1% clotrimazole cream is combined with 15gm of base. What is the new % strength ?

Answer 1

0.75% is the answer the our question

Answer 2

0.75 %

Explanation:

Given,

A 45 gm tube of 1% clotrimazole cream is combined with 15gm of base.

Since, the percentage of clotrimazole cream in base = 0 %,

Let x be the percentage of clotrimazole cream in the resultant solution,

So, we can write,

1 % of 45 gm + 0 % of 15 gm = x % of (45 + 15) gm

`\implies (1* 45)/(100)+(0* 15)/(100)=(x* 60)/(100)`

`\implies (45)/(100)+0=(60x)/(100)`

`\implies (45)/(100)=(60x)/(100)`

`\implies 45 = 60x`

`\implies x = (45)/(60)=0.75\%`
