Question
If ' X ' means '+', '+' means ' - ', ' - ' means '÷'
and '÷' means ' X ', what will be the value of the following expression? [{(84 - 3) ÷ 4} + (25 ÷ 5)] X 40Solution
Given expression: [{(84 - 3) ÷ 4} + (25 ÷ 5)] X 40 After replacing the signs, we get: [{(84 ÷ 3) X 4} - (25 X 5)] + 40 [{28 x 4} - (25 x 5)] + 40 [112 - 125] + 40 [-13] + 40 = 27 So, '27' will be the value of the given expression.
