Question: 1

In an imaginary language, the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 are substituted by a, b, c, d, e, f, g, h, I and j. And 10 is written as ba.
If P denotes +, Q denotes -, R denotes x and S denotes ÷, which of the following statements is correct?

(A) 36 R 4 S 8 Q 7 P 4 = 10

(B) 16 R 12 P 49 S 7 Q 9 = 200

(C) 32 S 8 R 9 = 160 Q 12 R 12

(D) 8 R 8 P S 8 Q 8 = 57

Ans: D

Using the proper notations in (d), we get the statement as

8 × 8 + 8 ÷ 8 = 8 × 8 + 1 - 8 = 64 + 1 - 8 = 65 - 8 = 57.

Question: 2

baf ÷ bf × d is equal to

(A) df

(B) cb

(C) be

(D) d

Ans: B

Given expression = 105 ÷ 15 × 3 = 7 × 3 = 21 = cb.

If ‘-’ stands for ‘division’, ‘+’ for ‘multiplication’, ‘÷’ for ‘subtraction’ and ‘x’ for ‘addition’ then when one of the following equations is correct?

(A) 4 × 5 + 9 - 3 ÷ 4 = 15

(B) 4 × 5 × 9 + 3 ÷ 4 = 11

(C) 4 - 5 ÷ 9 × 3 - 4 = 17

(D) 4 ÷ 5 + 9 - 3 + 4 = 18

Ans: A

Using the proper notations in (a), we get the statement as

4 + 5 × 9 ÷ 3 - 4 = 4 + 5 × 3 - 4 = 4 + 15 - 4 = 15.

Question: 4

dc × f - (bf - d) × d is equal to

(A) abb

(B) abe

(C) bce

(D) bcf

Ans: C

Given expression = 32 × 5 - (15 - 3) × 3

                    = 160 - 12 × 3 = 160 - 36 = 124 = bce.

Question: 5

bee + fg - (ca × h/be) is equal to

(A) bhc

(B) bic

(C) bib

(D) bja

Ans: D

Given expression = 144 + 56 - $$(20 × {7}/{14})$$

                    = 144 + 56 - (20 ÷ 2) = 144 + 56 - 10
