DECE1-UNIT1(TEST)-IGNOU-DAY9(ENG/HINDI)-ORSP

GIVEN :

Four times the first number is 10 more than thrice the second number.

CALCULATION :

Suppose the numbers are ‘a’ and ‘a + 1’.

According to the question :

4a = 3 × (a + 1) + 10

⇒ a = 13

Hence, the numbers are 13 and 14.

∴ Product = 13 × 14 = 182

Given:

The average of a group of 20 numbers is 30

The average of another group of 30 numbers is 50.

Formula Used:

Average = Sum of all observation/Number of observation

Calculation:

Let's assume the sum of the numbers in the first group as S1 and the sum of the numbers in the second group as S2.

According to the given information, the average of the first group of 20 numbers is 30, so we have:

⇒ S1/20 = 30

⇒ S1 = 20 × 30

⇒ S1 = 600

Similarly, the average of the second group of 30 numbers is 50, so we have:

⇒ S2/30 = 50

⇒ S2 = 30 × 50

⇒ S2 = 1500

To find the average of all the numbers in both groups, we need to calculate the total sum and the total count.

The total sum is the sum of the numbers in both groups, which is:

Total sum = S1 + S2 = 600 + 1500 = 2100

The total count is the sum of the number of elements in both groups, which is:

Total count = 20 + 30 = 50

Therefore, the average of all the numbers in both groups is:

Average = Total sum / Total count = 2100 / 50 = 42

Therefore, the correct answer is: 42

The correct answer is 'least'.

Key Points

• In the given sentence, "least" is the correct answer.
• In the given blank, we need a determiner "Least is the superlative form of little" and it can be used as a determiner with the uncountable noun followed by it.
  • For example- These farming methods cause the least damage to the environment.
• In addition to this, We use the quantifier "least" to talk about quantities, amounts, and degrees.
  • For example; He did the least work of any of us.
• In the given sentence, "Little" is incorrect because "the little" will also become a quantifier, and "amount of" will also become a quantifier hence, we don't need to use two quantifiers together. Hence, we will use a determiner i.e. "Least"

So the correct answer is- Lata has the least amount of milk.

The correct answer is 'Apparent'.

Key Points

• Correct sentence: He shouldn't have done it.
• Hence, the correct answer is option 4.

From the statements:

⇒ Baby is shorter than Anil.

Anil > Baby

⇒ Anil is taller than Sunny who is shorter than Baby.

Anil > Baby > Sunny

⇒ Anil is taller than Bose who is shorter than Sunny.

Thus, the final arrangement is as follows:

Anil > Baby > Sunny > Bose

We can see that Bose is the shortest.

Hence, Bose is correct.

Who is used for the second person in a connecting statement:

For example:

Anil is taller than Sunny, who is shorter than Baby → It means Anil is taller than Sunny and Sunny is shorter than Baby.

For this question, We have to check the given equation as-

146 –  2 + 3 × 123 × 5 + 2

New equation after replacing symbols-

146 ÷ 2 × 3 – 123 - 5 × 2

According to the BODMAS rule-

⇒ 73 × 3 –  123 – 5 × 2

⇒ 219 –  123 –  10

⇒ 86

Hence, Option (4) is correct.

Reverse alphabet series,

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A

12th letter from the left → O

8th to the right of the "O" → G

Hence, the correct answer is "G".

15 + (2)² = 19

19 + (4)² = 35

35 + (6)² = 71

71 + (8)² = 135

So, the correct option will be option 4.

Six Persons: S, T, U, V, W and X

Facing: North

1) W and T are sitting at the fourth position from the left end and the right end, respectively.

2) U and X are not the immediate neighbours of T and W.

3) S is sitting at the fifth position from the right end.

So, final sitting arrangement:

Hence, “V” is sitting at the second position from the right end.
