Answers
Answer:
30 is the answer because 30 + 30 + 30 - 90
Answer : Peter has 33 dollars
Step-by-step explanation:
let the money Peter has be x
now , according to the info
3x < 100 and 2x > 65
it means that the one more x added in the 2x will not exceed the sum more than 100 as 3x is < 100
as per the info 2x is more than 65,
let us assume that the 2x is 66......(1)
now
2x + x = 3x
therefore let us assume 3x as 99 (less than 100)
2x + x = 99
66 + x = 99....... from 1
therefore x = 33
33 matches every condition
double it will be 66 which is more than 65
tripple it it will be less than 100 that is. 99
if the x is 32 then
32*2 64 therefore it doesn't matches the second condition
again if the x is 34
then 34 x 2 is 68 and 34 x 3 is 103
which again does not match the first condition
hence our assumption is true
therefore the money which Peter has is 33$ as it fulfills every condition.
