number of ashoka trees by 60. If there are altogether 200 trees of these two types,
how many jambhul trees were planted ?
6. Shubhangi has twice as many 20-rupee notes as she has 50-rupee notes. Altogether,
she has 2700 rupees. How many 50-rupee notes does she have?​

Answer 1

Answer:

Step-by-step explanation:

5.

Given, Jambhul = Ashoka + 60

Also given,

Ashoka + Jambhul = 200

i.e. Ashoka + (Ashoka + 60) = 200

i.e. 2 x Ashoka = 140

i.e. Ashoka = 70

i.e. Jambhul = 70 + 60 = 130

6.

Let the number of 50 rupee notes be x.

Then, the number of 20 rupee notes is 2x

As per given information,

20 * (2x) + 50 * x = 2700

40x + 50x = 2700

90x = 2700

x = 30

i.e. Number of 50 rupee notes = 30

i.e. Number of 20 rupee notes = 2 * 30 = 60
