A) 7N
B) 8N
C) 9N
D) 12N
E) 20N

Ans:E

I need to know what is wrong in my approach below:
.........................

Let the total in 93 be 100
Then the total in 94 becomes 400(300% greater)
Now,it's said that the total in 94 was 400% greater than 92.so,
Let the total of 92 be x
x +400%x=400
x=80

so now we have the totals:
92:80
92:100
94:400

now,the question states that 80 = N
therefore total of 94, 400= 5N

hmmm..?

The expression that you have used:
Let the total in 93 be 100
Then the total in 94 becomes 400(300% greater)
This is correct but the later is incorrect because it is not the total in 94 that was 400% greater, total in 93 is 400% greater than 92. If 93 is 100,92 becomes 20(400%lesser),20=N,therefore total in 94 becomes 20N
Now,it's said that the total in 94 was 400% greater than 92.so,
Let the total of 92 be x
x +400%x=400
x=80

If 1992=$100
1993=$500 ($100 * 4) + $100
1994=$2000 ($500 * 3) + $500

1994=20*1992
