Question

If ‘ + ’ means ‘x’, ‘x’ means ‘+’, ‘-’ means ‘÷’ and ‘÷’ means ‘-’, then what is the value of 40 x 12 + 3 – 60 / 60 ?
​

Answer 1

Given: + = ×, × = +, - = ÷ and ÷ = -

Also given that, 40 × 12 + 3 - 60 ÷ 60

Now, change signs according to given data.

If we change signs according to given data, then we get

40 + 12 × 3 ÷ 60 - 60

Now, apply the BODMAS Rule on it.

B = Brackets, O = Of, D = Division, M = Multiplication, A = Addition and S = Subtraction

Means, first we have to solve brackets, then division, multiplication, addition and in last subtraction.

First: Division

→ 40 + 12 × 3 ÷ 60 - 60

→ 40 + 12 × 3/60 - 60

→ 40 + 12 × 1/20 - 60

→ 40 + 12 × 0.05 - 60

Second: Multiplication

→ 40 + 0.6 - 60

Third: Addition

→ 40.6 - 60

Fourth: Subtraction

→ - 19.4

Answer 2

Given :-

→ ‘ + ’ means ‘x’,

→ ‘x’ means ‘+’,

→ ‘-’ means ‘÷’

→ ‘÷’ means ‘-’,

To Find :-

• 40 × 12 + 3 - 60 ÷ 60 ?

Solution :-

Changing All Signs in Question According to Given :-

→ 40 × 12 + 3 - 60 ÷ 60 becomes :-

→ 40 + 12 × 3 ÷ 60 - 60

Now ,

→ According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.

So,

→ 40 + 12 × 3 ÷ 60 - 60

→ 40 + 12 × (3/60) - 60

→ 40 + (3/5) - 60

→ 3/5 + 40 - 60

→ 3/5 - 20

→ 0.6 - 20

→ (-19.4) (Ans).
