Question

Laila received 30 messages on her mobile phone 1 5 of them were picture messages snd 7 8 of the remainder were text messages the rest were voice messages
(A) How many text messages did she receive
(B) How many voice messages did she receive

Answer 1

A) To find the number of text messages, we first need to calculate the remainder after subtracting the picture messages from the total number of messages received.

30 messages - (1/5)30 messages = 30 - (6/30) = 30 - 6 = 24

So, Laila received 24 messages after excluding the picture messages.

Now, we will calculate 7/8 of the remainder to find the number of text messages.

(7/8)*24 = (7*24)/8 = 168/8 = 21

Therefore, Laila received 21 text messages.

B) The remaining messages after excluding the picture and text messages will be the voice messages.

Remaining messages = total messages - (picture messages + text messages)
= 30 - (6+21)
= 30 - 27
= 3

So, Laila received 3 voice messages.
