Question

Manju bought a bale of cloth at rs. x meter. She sold 40m cloth at rs. 105/m and the remaining at rs. 150/m and made 10% profit. How many meters of cloth had she bought in total?​

A) x=200
B) x=250
C) x=300
D) x=350
E) x=400

Answer 1

Manju cannot have bought a negative number of meters of cloth.

Step-by-step explanation:

To find the number of meters of cloth Manju bought in total, we need to solve the equation:

(40 * 105) + (x - 40) * 150 = x * 1.10

Where x is the total number of meters Manju bought.

Simplifying the equation gives:

4200 + 150x - 6000 + 6000 = 1.10x

Combining like terms:

150x + 600 = 1.10x

Subtracting 1.10x from both sides:

0.10x + 600 = 0

Subtracting 600 from both sides:

0.10x = -600

Dividing by 0.10:

x = -600 / 0.10

x = -6000

Since a negative value for x is not possible, we can conclude that there is an error in the given information or the calculations.
