Thank you. We compared 8u = 10400. So 1u = 1300. Then 90%=117000. This is different than our answer. May I request to explain more to improve our understanding.
That mean your 20% increase is equal 8u.
Then your 100% (last year) should be 40u. Therefore 40 x 1300 =52000.
Then your 100% (last year) should be 40u. Therefore 40 x 1300 =52000.
Can made it this way..
Let last year price = 1u
This year price = 1.2u (20% increased)
Given price increased by 10400
1.2u -1u =10400
0.2u =10400
1u = 10400÷0.2 =52000 (same as last year price)
Let last year price = 1u
This year price = 1.2u (20% increased)
Given price increased by 10400
1.2u -1u =10400
0.2u =10400
1u = 10400÷0.2 =52000 (same as last year price)
Thank you! Well understood. The answer price very low in Singapore market
Indeed too low for Singapore market.
I notice your question always very tricky. Now, I am wondering the question is asking price for last year before 10% decreased? :)
