A rectangular tank is 60 meters long and 40 meters deep.

If '-' means '÷', '+' means ' X ', '÷' means '-' and ' X ' means '+', then what is the value of the following expression?

Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.

28 * 174 * 6 * 4 * 126 = 18

If '+' means 'divided by', '-' means 'add', ' X ' means 'minus' and '÷' means 'multiplied by'. What will be the value of the following expression?

Which among the given operators should replace the “%” (in the same order) in the given expression below:

6 % 11 % 6 % 37 % 30 % 7
