a man sold two typewriters it 2970 each. if he gain 10% on one in 10% loss on father what is his gain or loss percent​
kipiarov [429]

original price of first typewriter = x  

2970/x = 110/100  

x = 2970 x 100/110 = 2700  

Price of first typewriter = Rs 2700  

Original price of second typewriter = y  

2970/y = 90/100  

y = 2970 x 100/90  

y = 3300  

Original price of second typewriter = 3300  

profit from first typewriter = 2970 - 2700 = 270  

Loss from second typewriter =  3300 - 2970= 330  

270 less than 330  

so he lost 330 - 270 = Rs 60 in whole transaction

I will never get the hang of these questions help

First term is -7, so a_1 = -7

To get the next term, we add on 4. We can see this if we subtract like so
d = (2nd term) - (1st term) = (-3) - (-7) = -3+7 = 4

So d = 4 is the common difference. 

Apply a_1 = -7 and d = 4 to get...
a_n = a_1 + d*(n-1)
a_n = -7 + 4*(n-1)
a_n = -7 + (n-1)*4
