What was the question for this implicit rationale, and corresponding answer?
If Raj has eaten 70 bananas in the basket, he has 2 * 70 = 140 bananas. The total number of bananas that Raj cut from the tree is 140 + 70 = 210. On the tree initially were 100 + 210 = 310 bananas.
 The answer: 310
The question: A banana tree has 100 bananas left after Raj cut some bananas from it. If Raj has eaten 70 bananas and has twice as many remaining in his basket, how many bananas were on the tree initially?
