Answers and solutions for Average Questions For Bank Clerk:

Solutions:

Required ratio = (40-34)/(34-30)=6/4=3/2

Let the numbers be a,b,c,d,e.
Hence (a+b+c+d+e)/5=49
(a+b)/2=48, a+b=96.
(d+e)/2=28,d+e=56
c=245-96-56=93

Let speed of train be x and speed of car be y.
Car covers 520km in 8 hrs, it’s speed= 520/8= 65km/hr
Speed of train = 3 * 65= 195km/hr
Distance covered by train in 13 hrs = 13*195= 2535km

The average weight of 21 boys is 64 Kgs.
The average weight of 21 boys and the teacher is 65 Kgs.
So, total weight of 21 boys is 21*64 = 1344
The weight of 21 boys and the teacher = 22*65 = 1430
Hence, the weight of the teacher is 1430 – 1344 = 86 Kgs
