Topic: Solve this question if you know you are good..

Smart Engineers. Any other question to solve?

@ Adexy007, u are the one at fault and not Yemmi. he got it right. Where u went wrong was wen u found a second value for y. Why would u need a second value when u already have y and z is an unknown?
U just av to do substitution and u get 11% * z = 50663.4 (this is y). Then u cross multiply and u get (50663.4*100)/11 = 460580 approximately.

Easy as ABC.

That means you didnt see what he outlined. Go back to it so that you see where he got 2 values of y. I didnt make it up.
You can say easy as ABC but yesterday I threw it here, you didnt say anything oo.. Na for hall you go know sey it's difficult as XYZ when your is hotting...lol

U didnt read it accurately. He found only one y. The second y he wrote was for you to substitute the value of y that had already been found.

I didnt respond earlier cos i just saw the post. I like such questions and always practice my shl type questions.

This is a very interesting thread. Adexy you have done a very good job, and all members who have responded. Please lets try and make some of this kind of thread.
