Hi readers,

Today I am sharing an important Data Interpretation Set for SBI Clerk Mains.

Today I am sharing an important Data Interpretation Set for SBI Clerk Mains.

### Directions:

**The following table gives the number of households in a country during the period 1970-90.**

**The following pie charts give the distribution of households based on the number of children for the year 1970 and 1990.**

## Ques 1.

Which of the following statements about the households is true ?

(a) There were more households with children in 1970 than in 1990.

(b) There were more households with 3 or more children in 1970 than in 1990.

(c) The number of households with two children decreased slightly from 1970 to 1990

(d) None of the above

**Ans 1.**No. of households with children in 1970

= ( 100-35/100 x 120) million = 78 million

No. of households with children in 1990

= ( 100-40/100 x 160) million = 96 million

Hence, statement (a) is not true.

No. of households with 3 or more children in 1970

=(25/100 x 120) million = 30 million

No. of households with 3 or more children in 1990

= (20/100 x 160) million = 32 million

Hence, statement (b) is not true.

No. of households with 2 children in 1970

= ( 20/100 x 120)million = 24 million

No. of households with 2 children in 1990

= ( 18 /100 x 160) Million = 28.8 million

Hence, statement (C) is not true

Thus, statement (d) is true.

## Ques 2.

The simple annual growth rate of number of households from 1970 to 1990 was

(a) 1.52%

(b) 1.65%

(c) 2.10%

(d) 3.00%

**Ans 2.**The required growth rate

= ( 160-120/120 x20 x 100)% = 1.65%( approx).

## Ques 3.

The average number of children per households in 1990 was

(a) 1.18

(b) 1.35

(c) 2.0

(d) Cannot be determined

**Ans 3.**The average number of children per house hold cannot be determined since one of the categories of households is ' households with > = 3 children'. In other words, we do not know the exact average figure for this category .Hence, the overall average cannot be worked out.

## Ques 4.

Assuming that the average number of children per households in 1970 was, how many households were without any children in 1970 ?

(a) 24 million

(b) 42 million

(c) 14 million

(d) Cannot be determined

**Ans 4.**No. of households without any children

in 1970 =m ( 35/100 x 120) million

= 42.0 million.
