Answer 1

Step-by-step explanation:

Hindustan Times is winning big in Mumbai with the number of readers going up to 14.35 lakh, which is more than that of Mumbai Mirror (10.98 lakh) and DNA (2.4 lakh) put together.

The Indian Readership Survey 2014, released on Friday, confirmed HT’s status as the number 2 English daily in Mumbai. HT’s readership is now close to two-thirds of Times of India’s. Moreover, HT Mumbai is more popular among young readers: 46% of HT’s readers are in the 12-29 age group as against 39% for ToI. And 9.11 lakh of HT’s readers do not read ToI. In fact, more than 50% of HT Mumbai’s readers do not read any other newspaper.
