Question

13. The dimensions of a rectangular box are in the ratio of 2:3 : 4 and the difference between the cost of
covering it with a cloth at the rate of 10 and 11 pet mis* 1,300. Find the dimensions of the box.​

Answer 1

Answer:

25, 50 & 100

Step-by-step explanation:

difference in the cost of cloth covering the rectangular box = Rs1300

[2lb + 2h(b + l) ]×(11 - 10) = 1300

2lb + 2h ( b + l) = 1300

2× 2x × 3x + 2×4x (3x + 2x) = 1300

52x = 1300 => x = 25

so the dimensions are

2x = 2(25) = 50

3x = 3(25) = 75 & 4x = 4(25) = 100
