Answer:
log 2 = 0.301
Step-by-step explanation:
We have to find the value of log 2 while the value of log 5 is given to be 0.6989.
Now, starting with log 10, we get,
log 10 = log (5 × 2) = log 5 + log 2
{Using the property of logarithm that, log AB = log A + log B}
⇒
⇒ log 10 = 0.6989 + log 2
{Since }
Again, we know that, log 10 = 1
⇒ 1 = 0.6989 + log 2
⇒ log 2 = 0.301 (Answer)
Answer:
2
Step-by-step explanation:
∵a+1,2a+1,4a-1 are in A.P.
2(2a+1)=a+1+4a-1
4a+2=5a
5a-4a=2
a=2
Answer:
ML
Step-by-step explanation:
It's just mirrored.
X+(4x-20)=180
=>5x-20=180
=>5x=200
=>x=40
<h3><u>Solution: </u></h3>
Overall<u> </u>CP of each fan = ₹1200 .
One is sold at a loss of 5% .
- ( This means if CP is ₹100, SP is ₹95 ) .
• Therefore,When CP is ₹1200 , Then SP is ₹ 1140.
Also,Second fan is sold at a profit of 10% .
- It means , If CP is ₹100 , SP is ₹110.
Therefore , When CP is ₹1200 , Then SP is ₹1320.
<u>• We need to find the combined CP and SP to say whether there was an overall profit or Loss.</u><u>.</u>
- Total CP = ₹ 1200 + ₹ 1200 = ₹ 2400.
- Total SP = ₹ 1140 + ₹ 1320 = ₹ 2460.
Since total SP > total CP , A profit of ₹ ( 2460 - 2400 ) or ₹60 has been made ..
