4. If ‘÷’ means ‘x’, ‘x’ means ‘+’, ‘+’ means ‘-’ , ‘-’ means ‘÷’ then,

a)– 72

b)- 69

c)– 79

d)- 88

b)- 69

Put the proper sign in the given equation we get

= -69

5.Some equations have been solved on the basis of a certain pattern. Find the correct answer for the unsolved equation in the basic.

a)8436

b)2184

c)3180

d)2526

a)8436

In the given equations

5 x 3 x 2 = 1510

First number is multiplied with second number and gives 15 then First number is multiplied with Third number and gives 10

Similarly

12 x 7 = 84

12 x 3= 36

Therefore 12 x 7 x 3 =8436
