At disc of 10% there was 5rupees loss and at disc of 5 % dis there was 22.5 profit
so 5% *x= 22.5+5=27.5
x=27.5 *20
x=550
Answer:
10ac
Step-by-step explanation:
We have been given the expression a · c · 5 · 5
We can multiply 5 with 5 and get 25.
Thus, the expression becomes
a · c · 5 · 5= ac25
We can rewrite the expression using commutative property
25ac = 25ca
Therefore, the given expression is equivalent to 25ac and 25ca.
Hence, 10ac is not the correct form.
First option is correct.
11,900,000,000 = 1.19 x 10^10
