Hazrat Younas (A.S) remained in the belly of the fish for: A) 20 days B) 30 days C) 40 days D) 50 days
A square region has an area of 2304 m. Find its perimeter? A) 24 m B) 96 m C) 144 m D) 192 m Solution A square region has an area of 2304 Let side of the square be x. By using the formula x2 Hence x2=2304 x=48 Hence the perimeter = 4 * side=4x =4*48 =192m
Cooking gas is mixture of which of the following two gases? A) Methane & Carbon dioxide B) Oxygen & Nitrogen C) Butane & Propane D) Oxygen & Methane
A man rows to a place 48 km distant and come back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is: A) 5 km/h B) 4 km/h C) 3 km/h D) 1 km/h Solution Suppose he moves 4 km downstream in x hours. Then,Speed downstream =(4/x) km/hrSpeed upstream =(3/x) km/hr∴48/(4/x)+48/(3/x)=14 or x=1/2So, Speed downstream = 8 km/hr, Speed upstream = 6 km/hr.Rate of the stream =1/2(8−6)km/hr=1km/hr
In a 100 m race A covers the distance in 36 seconds and B in 45 seconds. In this race A beats B by: A) 20 m B) 24 m C) 28 m D) 30 m Solution A covers 100 m in 36 seconds In same 36 seconds B would have covered 100*36/45=80 m So A beats B by 100–80=20 m
