SSC CPO 12 Mar 2019 Shift 1 Paper

After starting from her house, Sameera walked a few metres towards the East. From there, she took a right turn and she walked 100 m, and then took a left turn and walked 30 m. Finally, she took a left turn again and walked 40 m to reach the market. If the air distance between her house and the market is 100 m, how far did Sameera walk towards the East initially from her house?
