Question

A sum of Rs 140 is divided into two parts. If the greater part is Rs 20 more than the double of smaller part, find the parts of the sum.​

Answer 1

Let smaller part be x
x+20+2x=140
3x=120
x=40
Larger part=40(2)+20=100

Answer 2

Step-by-step explanation:

• let the greater part be X and the smaller part be Y
• so the equation will be
• X+Y=140 AND X=20+2Y
• Substituting the value of equation 2 in equation 1
• 20+2Y+Y=140
• 20+3Y=140
• 3Y=140-20
• 3Y=120
• Y=120/3
• Y=40 and X=20 +2(40)=20+80=100
• SO X=100 AND Y=40
