Answer:
Rs 175
Step-by-step explanation:
Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).
At Rs200, the profit is 200-x.
So we have an equation: minus 150 minus x is equal to 200 minus x.
To solve the equation, the cost price X is Rs175.
7. general term of gp is given by ar^n-1
hence,4th term is given by
ar^3=15 ------(1)
ar^6=405-----(2)
equation 2/1,we get
r^3=27
so common ratio r=3
putting value of r in equation 1,
we get a=5/9
so gp upto 7 terms will be 5/9,5/3,5,15,45,135,405
8. a=3
given 4th term is -24
so ar^3=-24
substituting value of a we get r^3=-8
r^3= -2^3
so r = -2
using this x2 is ar= 3*-2=-6
x3 is ar^2= 3*4=12
