Monthly salary = Rs. 7000
Then money earned in the 1st year = 7000*12 = Rs. 84000
Annual increment = Rs. 500
Money earned in the 2nd year with increment =7500*12 = Rs. 90000
Now for 3rd year = 8000*12 = Rs.96000
So, here
a = Rs. 84000
d = Rs. 6000
n = 10 years
Sn = n/2{2a + (n - 1)d}
S₁₀ = 10/2{2*84000 + (10 - 1)6000}
= 5{168000 + 54000}
= 5*222000
= Rs.1110000

Karunesh Kumar Mishra 5 years, 6 months ago

Let we assume that 2-√3 is R.N Therefore, it can be written as 2-√3=p/q => 2-√3= p/q => p - 2q/q = √3 since, p and q are integer Therefore, p/q is R.N Therefore, p - 2q/q is also a R.N Therefore, √3 is also a R.N But we know that √3 is irrational number Here is a contradiction So, we finally say that 2 - √3 is irrational number

Shravani ? 5 years, 6 months ago

You should first have to assume that √5 is rational √5=p/q that is p=√5q Squaring on both side p2=5q2 P2/5=q2 :.P2is divisible by 5 :.p is also divisible by 5 P=5 are for some integer=r Squaring on both side p2= 25r2 Then it became 25r2=5q2 r2=5q/25 r2=q2/5 Again q2 is divisible by 5 And q is also divisible by 5 Then we have to write reason that 5 is coom factor and p&q are co-prime. This codradiction has arise because of our incorrect assumption so we consider that root 5 is irrational number .
