Step-by-step explanation:
Find 10%:
100% = 2500
1% = 2500 divide 100
= 25
10% = 25 x 10 = 250
Find the 13% vat:
13% = 25 x 13 = 325
Find the total amount he got charged:
325 + 250 = 575
Total amount he had to pay for dinner + charges:
2500 + 575 = 3075
Answer: Rs. 3075
The given problem is very confusing since it was copy
pasted directly from the source so the equations look scrambled and plus it was
one words. After my own translation, I believe the given numbers are:
4 ⋅ 10^6
and
1 ⋅ 10^4
The symbol ⋅ means
that the two numbers are multiplied while the symbol ^ means an exponent of.
Now we are asked to find how much the 1st number is larger than the
2nd number. To solve this, we simply have to divide the bigger
number by the smaller number. Since 4 ⋅ 10^6
has bigger exponent than 1 ⋅ 10^4
then it is the bigger number.
Ratio = 4 ⋅ 10^6 /
1 ⋅ 10^4
Ratio = 4 ⋅ 10^2 =
400
Therefore 4 ⋅ 10^6
is 400 times bigger than 1 ⋅ 10^4.
