What is the distance in miles of her office from her house ? Correct Answer 10 Let the distance and time be d mile and T hours respectively. So,  d = 4T. Again,  d = (4 + 1) (T - 1/2) or,  4T = 5(T - 1/2) or,  4T = 5T - 5/2 or,  5T - 4T = 5/2 or,  T = 5/2 hours So,  d = 4T = 4 x 5/2 = 10 mile.

Explanation:

X purchased some pens for TK. 120 . If the price per piece of pen was TK. 3 less, he would have received 2 more pens. How many pens did he purchase ? Correct Answer 8 Let the number of pens be N. Then, price of each pen = 120/N He would get (N + 2) pens if the price of each pen was [120/N - 3]. So,  120 / (N + 2) = (120/N) - 3 or,  120 / (N + 2) = (120 - 3N) / N or,  120N = (120 - 3N) (N + 2) or,  120N = 120N + 120 x 2 - 3N2 - 3N x 2 or, 3N2 + 6N + 120N - 120N - 240 = 0 or, 3N2 + 6N - 240 = 0 or, N2 + 2N - 80 = 0 or, N2  + 10N - 8N  - 80 = 0 or, N(N + 10) - 8(N + 10) = 0 or, (N + 10) (N - 8) = 0 or, N - 8 = 0 [N + 10 = / 0] So, N = 8
