Rema walked 10kms south and turned right and walked 5kms. Then again she turned right and walked 10kms. Then she turned left and walked 10kms. How many kms will rema have to walk to reach the starting point?
Let Rema started from point A, she walked south for 10 km and reached point B, then she turned right and walked towards west for 5 km and reached C. Then, she turned left and reached DÂ after walking for 10 km and finally again turned left and stopped at point E after walking 10 km.
Thus, AE = 10 + 5 = 15 km
=> Ans - (D)
