interest paid is Rs. 1200, how much should each receive?

Answer 1

1. 8000x9÷10000×12
2. 72÷120
3. 3/5
4. 3+5=8
5. 1200x3/8=450
6. 1200×5/8=750

Answer 2

Step-by-step explanation:

given , Ahmed

p=8000

time=9months =3/4 years

Muneeb,

p=10000

time=12months=1years

putting together

some of interest of Ahmed and Muneeb

we all know that formule,

• SI=p*r*t/100
• some if interest of ahmed +muneeb
• p*r*t/100 + p*r*t/100 =Rs.1200
• 8000*r*3/4/100 + 10000*r*1/100=1200
• r*60 + r*100 =1200
• 60r+100r=1200
• 160r=1200
• r=15/2
• for ahmed+ahmed
• p*r*t/100 +p*r*t/100
• 15/2(8000*3/4/100 + 10000*1/100)=1200

• 1200=1200
• so,ahmed lend interest=3/4 of 1200=900,1200-900=300
• ahmed left one 1200-300=900
• gets 300 as interset and muneeb gets900
• as interest
• ahmed amount=8000+300=8300
• Muneeb amount=10000+900=10900
