Answer:
15 meters and 25 meters long
Step-by-step explanation:
<em>There are 2 pieces of rope</em>.
Total length of both---> 40 meters
Length of piece 1 ------> x
Length of piece 2 -----> x + 10
<em>Find the value of x.</em>
<em>Form an equation ----> Length of piece 1 + length of piece 2 = total length</em>
x + (x + 10) = 40
2x + 10 = 40
2x = 30
x = 15
Length of piece 1 --> x ---> 15
Length of piece 2 --> x + 10 ----> 15 + 10 = 25
Therefore, one piece is 15 meters long and the other piece is 25 meters long.

Answer:
605 rupees
Step-by-step explanation:
add the parts of the ratio 3 + 4 = 7
divide the number of notes by 7 to find one part of the ratio
= 11 ← 1 part of the ratio
3 parts = 3 × 11 = 33 ← number of 5 rupee notes
4 parts = 4 × 11 = 44 ← number of 10 rupee notes
Amount of money = (33 × 5 ) + (44 × 10) = 165 + 440 = 605 rupees
