Question

There are 2a number of passengers on a train. At the next junction, another 15 passengers catch the train. There are a total of 150 people on the train.
Write the algebraic equation for the above comprehension.

• A. 150 = 2a + 15$
  
• B. $150=2a+15$
  
• C. $150=2a-15$
  
• D. $150=2a\times 15$
  

Answer 1

The correct option is A 150 = 2a + 15$


Given,
Initially, the number of passengers on the train $=2a$

At the next junction, the number of passengers caught the train = 15

Total number of passengers on the train = $150$

Hence,
Total number of passengers on the train = the number of people on the train intially + the number of passengers caught the train at the next stop
$\Rightarrow 150=2a+15$
