Ram is younger to Harsh by 9 years. If their ages are in the respective ratio of 4:5, how old is Ram?

Detailed Solution for APPSC (Arunachal Pradesh) Prelims Paper 2 Mock Test- 3 - Question 7

APPSC (Arunachal Pradesh) Prelims Paper 2 Mock Test- 3 - Question 8

Shubh is 30 years old and Niku is 25 years old. How long ago was the ratio of their ages 3: 2?

Detailed Solution for APPSC (Arunachal Pradesh) Prelims Paper 2 Mock Test- 3 - Question 8

Here, we have to calculate: How many years ago the ratio of their ages was 3:2. Let us assume x years ago

At present: Shubh is 30 years and Niku is 25 years

x years ago: Shubh’s age = (30 – x) and Niku's age = (25 – x)

Given, the ratio of their ages was 3:2 

Solving, we get: x = 15

Therefore, the answer is 15 years.

APPSC (Arunachal Pradesh) Prelims Paper 2 Mock Test- 3 - Question 17

In a poor country like India, as income rises people first concentrate on increasing their consumption of what they regard as basic or more essential consumer goods. For the poor, these goods would primarily include cereals and for people at successive levels of higher income protective foods, simple non-food consumer goods, more modern, better quality non-food consumer goods and simple consumer durables, better quality consumer goods, and so on. When the demand for basic and more essential consumer goods is more or less met, demand for the next higher level of consumer goods begins to impinge on consumer decision making and their consumption increases. There is thus a hierarchy of income levels and a hierarchy of consumer goods. As incomes rise and one approaches the turning point referred to, there is an upward movement along the hierarchy in the demand for consumer goods which exhibits itself in a relative increase in the demand for these goods. If one examines the past consumption behaviour of households in India, one finds confirmation of the proposition just made. Until the mid seventies one notices a rise in the proportion of consumption expenditure on cereals, and thereafter, a steady decline reflecting a progressive increase in the relative expenditure on non-cereal or protective foods. About the same time the rising trend in the share of food in total consumption expenditure also begins to decline, raising the proportion of expenditure on non-food consumer goods. Simultaneously one also notices a sharper rise in the proportion of expenditure on consumer durables. Thus, what one sees is an upward movement in consumer demand along the hierarchy of consumer goods which amounts to a major change in consumer behaviour.

Detailed Solution for APPSC (Arunachal Pradesh) Prelims Paper 2 Mock Test- 3 - Question 22
For the least possible number of casks of equal size, the size of each cask must be of the greatest volume.

To get the greatest volume of each cask, we have to find the largest number which exactly divides 435, 609 and 290.That is nothing but the H.C.F of (435, 609, and 290)

The H.C.F of (435, 609, 290) = 29 litres

Each cask must be of the volume 29 litres.
