1 Answer

Answer :

E

 Where x is the initial quantity of milk in the cask y is the quantity of milk withdrawn in each process and n is

the number of processes.

Initial quantity:55

Withdrawn quantity=5.5 number of times repeated=3

Hence from the above rule it can be say that,

Formula,=[a(1-b/a)n

]

Quantity of milk left after the 3rd operation =55*((55-5.5)/55) ^3

 =40.09litres.

SoAmit's age 8 years ago = (y + 18 - 8) Rohit's age before 8 years = (y - 8) 8 years ago, Amit is 6 times as old as Rohit (y + 18 ... = 58 y = 11.6 Rohit's age = 11.6years Amit's age = (y + 18) = (11.6 + 18) = 29.6years

A mixture contains milk and water in the ratio of 3:2 litter of water is added to the mixture, milk, milk and water in the mixture become equal find the quantities of milk and water in the mixture . a) 12, 8 litter b) 4,3 litter c) 12, 6 litres d) 10,8 litres e) None of these

Description : A mixture contains milk and water in the ratio of 3:2 litter of water is added to the mixture, milk, milk and water in the mixture become equal find the quantities of milk and water in the mixture . a) 12, 8 litter b) 4,3 litter c) 12, 6 litres d) 10,8 litres e) None of these

Last Answer : Let quantities of milk and water in the mixture be 3x and 2x. Then if 4 litres of water is added to the mixture the ratio of milk and water become 1:1. It can be written as (3x): (2x + 4) = 1 ... Therefore, the milk in the mixture is 4x3 = 12 litres and quantity of water = 4x2 = 8 liters Answer: a)

Description : Number of teeth which are replaced in man are – (1) 12 (2) 20 (3) 32 (4) 16

Last Answer : (1) 12 Explanation: Deciduous teeth are the first set of teeth in the growth development of humans and many other mammals. The deciduous teeth are: incisors (4); molars (6); and canine (2). So there are 12 teeth which get replaced by the age of 12 when only permanent teeth remain.

Two trains are running at 40 km/hr and 20 km/hr respectively in the same direction. Fast train completely passes a man sitting in the slower train in 5 seconds. What is the length of the fast train? A.27 7/9 m B.28 m C.29 m D.30 2/7 m E.None of these

Description : Two trains are running at 40 km/hr and 20 km/hr respectively in the same direction. Fast train completely passes a man sitting in the slower train in 5 seconds. What is the length of the fast train? A.27 7/9 m B.28 m C.29 m D.30 2/7 m E.None of these 

Last Answer : Answer – A (27 7/9 m) Explanation – When SAME direction- MINUS Relative speed = (40-20) km/hr = [20 x 5/18] m/sec = [50/9] m/sec. Length of faster train = sxt=[50/9 x 5] m = 250/9 m = 27 7/9 m.
