Here is your code:

#define mpu6050_I2C_ADDR		0X11

But the I2C addresses of mpu6050 can be 0x68 or 0x69. Where did 0x11 come from?

[nordicbeginner]

yes i am saying that whether i write 0x68 or 0x69 or 0x11 i am getting 0x18 every time

You should look at mpu6050 datasheet. When AD0 is low, its address is 0x68, and when AD0 is high, its address is 0x69.

i know it i am saying that i have tested it with 0x69 and 0x68, but not getting correct value
