For the first 50 pages of Rob’s report, he paid 10 x 50 = 500 dollars.

For the next 70 pages, he paid 7 x 70 = 490 dollars.

He paid 70 x 4 = 280 dollars for the first iteration of 70 pages.

He paid 20 x 3 = 60 for the second iteration of 20 pages.

In total Ross paid: 500 + 490 + 280 + 60 = 1,330 dollars,

so 120 pages.. first 50 page 10 and next $$70@7 = 50*10+70*7= 990$$..

Iteration....this is where one can go wrong
one iteration $$50@4=200$$
two iteration $$20@(4+3) = 20*7=140$$..

total = $$990+200+140=1330$$

C

Is it ok that it is not mentioned in a passage that 20 pages with 2 iterations were not from the set of 50 pages with 1 iteration?
Because if we do so, we get 1250 - option B.

I have the same doubt. Could someone please verify?
Will those 50pages be exclusive of the 20 pages needing 2 iterations ?
