Test Paper: Mathematical Operations

Mathematical Operations
11.      If ‘+’ stands for division; ÷stands for multiplication; ‘X’ stands for Substraction; ‘_’stands for addition, which one of the following is correct?
a.     18÷6-7+5×2                  =20
b.     18+6÷7×5-2                =18
c.      18×6+7÷5-2              =16
d.     18÷6×7+5-2            =22

22.     If + means ‘minus’ –means ‘multiplied by’; ÷ means ‘Plus’ and × means ‘divided by’ then
10×5÷3-2+3=?
a        a.  5               b. 21                     c. 53/3                                               d. 18

33.     If + stands for Division X stands for ‘addition’,  ‘–‘ stands for multiplication and ÷ stands for substraction, then which of the following equations is correct?
a.     36-6+7x5÷3=74
b.     36 x6+7÷2-6=20
c.      36+6-3x5÷3=24
d.     36÷6+3 x5-3=45

44.     The symbols for addition (+), substraction(-), multiplication(x) and division(÷) will have to be inserted in the blank squares in order to get answers as shown in the equation:
20         5    5                8           2          17 =3
Find out which set below is correct?
1.     - + ÷ X             3. X- ÷+
2.     + - X  ÷           4. ÷+ X-

55.     The letter to be inserted in the relation given
OX?+P=43

   a.    L                    b. M                   c. N                                              d. K

66.    A stands for ‘addition’, B for ‘Substraction’ C for ‘Division’ D for ‘multiplication’ and E for ‘less than; F for ‘greater than’ and G for ‘equal to’ out of the alternative only one expression in correct according to there letter symbols identify that

a.     18C2A4B6G9
b.     6d4B12A4C2F18
c.      10C2D4B6E12
d.     9A7B4C2G14

7.7.     If P denotes +, Q denotes -, R denotes ÷, and S denotes X, then
18s36R12Q6P7=?
a.     115               b. 25                    c. 55                        d. 648/13

8→stands for +, ← stands for -, ↑ stands for ÷, ↓ stands for X, ↔ stands for =, which one is correct?

a.     2↓5←6→2 ↔6
b.     5→7←4↑2↔3
c.      3↓6↑2 →3←6↔5
d.     7←43↑6↓1↔4
