A. 42, 28
B. 36, 24
C. 30, 20
D. 25, 15

Let the present ages be 6x and 4x where x is a common factor to both.
Five years ago, A will be 6x-5 while B will be 4x-5
Then 6x-5 / 4x-5 = 5/3
Cross multiply
3(6x-5) = 5(4x-5)
18x-15 = 20x - 25
-15+25 = 20x - 18x
10= 2x
X= 5

Present ages
A=6x = 6x5 = 30
B = 4x = 4x5 = 20

P.S: If person dey exam hall, just use d available answers to check and get d correct one, no time to waste.

And = C (30, 20).

explanation:

Two equations are important here:
Let their Present ages be x and y respectively. Based on that, we have:

1st --- 6/4 = x/y
4x = 6y

2nd equation from second statement:

5/3 = x - 5/ y - 5
3x - 5y = - 10.

Solve for x and y respectively and you'll have X = 30 and Y = 20.

My opinion though. I stand to be corrected.

Your head is there!!!

I guess what they mean by original is that, it shouldnt be photocopied, like the black and white thing. Temporary voter's card has the same ID number as the permanent ones.

Christuff:

Pls can you give d options, cos am getting 3240,let me confirm

the answer is 2088

scobyy2007:

Average Cost = Total Cost / Quantity
Total Cost = Average * Quantity
T1 = 36 * (5+4) = 324 T2 = 48 * (7+8 ) = 720
T1 + T2 = 1044 for total of 24 Quantities
Hence The Total Cost of 48 will be 2088

thanks

Kayceenaz:

If: 12 oranges (7+5) and 12 guava (8+4) =84 naira (48+36) In other words, 24 fruits=84 naira
Then: 24 oranges and 24 guava (48 fruits)=168 naira
Therefore, the total cost of 24 oranges and 24 guava is 168 naira.

wrong

Jarus:


This is what is called word problem. Let me help you translate it from word to equation:

If (5x+4y)/9=36

and (7x+8y)/15=24

Find 24(x+y)

That is what that sentence is saying.

Complete it yourself.

thanks bro

For your information, don't kill yourself because of this NNPC aptitude test. Many will qualify for the next level (eg I will) while many will end their journey after the test.
Read and stick to the following instructions

1. If you are to travel to another state where you don't have anyone to stay with, don't spend too much on lodging and hotels or buying new suits and shoes for the test.
2. This is just test not the actual interview. Later, many will regret why they honoured the invitation. It has been happening.
3. Bargain like a grandma before you enter cab or bus. They may not refund you.
4. Eat before you go for the exam. They may not give us food there.
5. Drop off your phones and bags before going to the exam venue. The security man will keep it for you and charge you.
All I'm saying is spend your money wisely as you go for the test. You have not yet been employed
Add to my point if you have any...
