if x is the original price,

price after 15% discount = (x-0.15x)=68
solving for x, we get x=80

after 25% increase on the discounted price,
new price = 68+68*25/100 = 85

therefore difference in original and new price =$5
(option d)

this problem is easier to solve using venn diagram. Please refer to the attached image. from the given information D+A+X+C = P = 22 F+A+X+B = H =27 E+B+X+C = W = 28 (D+F+E) + (A+B+C) + X = 59 A+B+C=6 adding first 3 equations, (D+E+F)+2(A+B+C)+3X=77 Subtracting the above equation from the 4th equatio...

IMO E.

the beginning of the sentence states "each year" .. hence the word "annually" is redundant. Options A, B and C are out.

between D and E, Option E is the best.

i think you could solve this problem algebrically than picking the numbers. the triangle mentioned in the problem is an equvilateral triangle with side T and the area of an eq. triangle is [(square root of 3)*T^2]/4 and the area of a square with side S = S^2 given that area of eq. triangle = area of...

raunekk,

in the example you selected, the correct idiom is being used:
So X as to be Y

however, in the original sentence you posted, "so as to" is not being used as an idiom and hence is incorrect. hope this helps.

among all the available options D looks better than others.
imo D.

i found a similar post and the OA is A.

Take a look..

This is a modifier problem. The modifying phrase A prolific architect who worked from the turn of the century until the late 1950’s , is modifying the noun Julia Morgan - who is described as the prolific architect. Hence A is the correct option. None of the other options modify the noun - Julia Morg...
