If the profit is 25%, then the value of x is #### Select the correct answer Solution! Let!C.P. of each article be Re. 1 C.P. of x articles = Rs. x.! !S.P. of x articles = Rs. 20.! !Profit = Rs. (20 - x)! !So, (20-x)/x * 100 = 25!2000 - 100x = 25x!125x = 2000! !Hence, x = 16. #### Question No 4 A train 108 m long moving at a speed of 50 km/hr crosses a train 112 m long coming from opposite direction in 6 seconds. The speed of the second train is #### Select the correct answer Solution! Let the speed of the second train be x km/hr.! !Relative speed = (x + 50) km/hr!= (x+50)*(5/18) m/s!= (250+5x)18 m/s! !Distance covered = (108 + 112) = 220 m! !So, 220/[(250 + 5x) /18] = 6!250 + 5x = 660! !Hence, x = 82 km/hr. #### Question No 5 Meena is thrice as old as Sheraz.

If the speed of the boat in still water is 10 mph, the speed of the stream is #### Select the correct answer Solution! Let the speed of the stream x mph.! !Then,!Speed downstream = (10 + x) mph! !Speed upstream = (10 - x) mph! !So, [36/(10 - x)] - [36/(10 + x)] = 90/60!(72x)*60 = 90 (100 - x*x)!(x+ 50)(x - 2) = 0! !Hence, x = 2 mph.. #### Question No 12 If P$ Q means P is the father of Q; P # Q means P is the mother of Q and P * Q means P is the sister of Q, then N # L \$ P * Q shows which of the relation of Q to N?
