Question

pls answer this it helps me

Answer 1

Step-by-step explanation:

first take out 1/3 of 300 that will be a 100

then subtract it from money that will be 200

then 1/4 of 200 is 50

so money left is 300-100-50=150

Answer 2

Answer:

1) A rational number between 3 and 4 is 1/2 (3 + 4) = 7/2

2) =Rs.150  

Step-by-step explanation:

1) Then, 3 < 7/2 < 4

A rational number between 3 and 7/2 = 1/2 {3 + 7/2} = 1/2 (3/1 + 7/2)

= 1/2 ((6 + 7)/2) = (1/2 × 13/2) = 13/4

A rational number between 7/2 and 4 = 1/2 {7/2 + 4} = 1/2 (7/2 + 4/1)

= 1/2 ((7 + 8)/2) = {1/2 × 15/2} = 15/4

Therefore, 3 < 13/4 < 7/2 < 15/4 < 4

Hence, 13/4, 7/2 and 15/4 are the three rational numbers lying between 3 and 4

2) Money spent (1/3)*300

=300/3

=Rs.100

She spent Rs. 100 on her notebooks

Money remaining with her after purchasing notebooks will be 300-100=Rs.200

She spent 1/4 th of the remaining money on stationary items

Money spent on stationary items will be (1/4)*200

=200/4

=Rs.50

The money remaining with her is 200-50

=Rs.150

Hope it helps!!!
