hi
Step-by-step explanation:
1+1=2
Step-by-step explanation:
when the difference between CI and SI given then the sum =
difference (100/r)^2
given difference is Rs . 180
Rate of interest is 15%
sum = 180× (100/15)^2
180×10000/225
= 8000
5x + 2 -x = -4x
4x +2 = -4x
2 = -4x -4x
2 = -8x
x = - 1/4
hope this helps
