According to the question

$x+ \: \frac{36x}{100} = 3400000 \\ \frac{100x + 36x}{100} \: = 3400000 \\ \frac{136x}{100} = 3400000 \\ x = 3400000 \times \frac{100}{136} \\ x =2500000$

Answer 2

Let the required cost be = X According to the Question

X + 36xupon 100 = 3400000
100x + 36xupon 100 = 3400000
