Answer:
Each orange costs 0.26 and each apple costs 0.32.
Step-by-step explanation:
12 oranges and 7 apples cost 5.36.
And the cost is 3.68 for 8 oranges and 5 apples.
If each orange costs x and each apple cost y then we have the equations
12x + 7y = 5.36 ..... (1) and
8x + 5y = 3.68 ........ (2)
Now, solving equations (1) and (2) we get,
15y - 14y = 3.68 × 3 - 5.36 × 2
⇒ y = 0.32
Now, from equation (2), we get 8x + 5 × 0.32 = 3.68
⇒ 8x = 2.08
⇒ x = 0.26
Therefore, each orange costs 0.26 and each apple costs 0.32. (Answer)
Answer:
Let 3rd digit be x
then 2nd digit = 4x & 1st digit = 4x-2.
It is three digit number. So, there are two case either x=1 or x=2.
Case 1,
3rd digit = 1, 2nd digit = 4 & 1st digit = 4–2=2
Hence number = 241 (ans)
Case 2,
3rd digit = 2 ,2nd digit 8 & 1st digit = 8–2=6.
Hence number = 682 (ans).

Given situation:
Mr. jones received 70% of the 1500 vote casts in an election
Question and solution
=> How many votes did Mr Jones received:
=> 1 500 is the total number of voters and 70% of it voted Mr. Jones.
SO let’s start solving to get the number of voters who voted him.
=> 70% = 70 / 100 = .70
=> 1 500 * .70
=> 1 050 , the number of voters who voted him in an election.
