Question

Answer 1

Given that the price of the eggs is reduced by 40%.

Actual reduction (savings) in price for every $ 50 spent = 50 * (40/100) = $ 20

And for this $ 20 saved (reduction in price), the women got 64 more eggs.

$ 20 --- 64 eggs     

? $   --- 12 eggs     (since we are interested in dozen eggs)     

Reduced price per dozen eggs X = (  ( 12 * 20 ) / 64 ) = $3.75

So, with the discounted price, the women saves $3.75, for every dozen eggs purchased.

Option: 2

It says 'reduced to 40%'. Doesn't that mean we should take 'reduced by 60%' in our solution?

 I understood the rest part of the solution. Thanks

Really appreciate you for raising this and you are absolutely right that when it is given ‘reduced to X%’, then actual reduction in price will be (100-X)%.  

In this case, would could have followed the same had if we had ‘None’ as one of the options, with the required answer for ‘reduced by 60%’ is missing.

So driven by options, I presumed that, they actually wanted to convey that, the price is reduced by 40%. and I just tried to highlight what i'm considering as actual reduction, with first line of the solution .

Please do let me if i'm still missing something here..

Answer 2

Let the original price be Rs x. Then reduction is done by 40%.

So d reduced price will be

x-40% of x. Therefore d reduced price is 0.6x.

64 more eggs cud be purchased for this given price.

So working out

50/0.6x -50/x=64/12

20/0.6x=64/12.

I literally worked out many times and I m getting d answer to be 6.25 which matches none of d options. So if u know any other method please mention it here.

I'd actually want to know wat d real answer is.:). Yeah!! Do share.

@devshree,6.25 is the original prize per dozen,and we need to calculate revised prize per dozen
