View answer & explanation

Correct answer

Answer: (c)C.

85

Why this answer is correct

Given :  23 B 4 D 63 A 3 C 14 = ?

'A' stands for '÷', 'B' stands for 'x', 'C' stands for '+' and 'D' stands for '-'

23 x 4 - 63 ÷ 3 + 14 = ?

92 - 21 + 14 = ?

92 + 14 - 21  = ?

106 - 21  = ?

Hence, the correct answer is "Option 3"

Question 473

IB MTS 2025• Test

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Conclusions:

(I) Some bats are ruffles.

(II) Some ears are ruffles.

  1. AOption (a)

    Only conclusion (II) follows.

  2. BOption (b)

Correct answer

Answer: (a)A.

Only conclusion (II) follows.

Why this answer is correct

The least possible Venn diagram is as follows:

Conclusions:

(I) Some bats are ruffles.- False (As their is no direct relation between bats and ruffles  may be it is possible but not definite. Hence, it is false)

(II) Some ears are ruffles.- True (All ruffles are ears.Some ruffles are ears. Some ears are ruffles is True)

Only conclusion (II) follows.

Hence, the correct answer is "Option 1"
