Question 4 : The average daily temperature from 9th January to 16th January (both inclusive) was 38.6 degree and that from the 10th to 17th January (inclusive) was 39.2 degree . What was the temperature on 17th January?
Question 3 .......
1. Let m be the number.
After 20% deduction, the number becomes (4/5)m.
30% of Remainder = (3/10)x(4/5)m = (12/50)m = (6/25)m.
Remaining = (19/25)m.
(19/25)m=3500.
m = 4605 approximately.
Therefore, original sum is 4605 approximately.
But My ans Is
after 20% deduction number become 80m\100 , then 30 % deduction from 80m\100 number become 50m\100
So 50m\100 =3500 so m = 7000
How original price is ,120\100 *120 ?
Question 2 steps show
Your ans is different
Yes after 20% deduction number become 80m\100 , then 30 % deduction from 80m\100 number become 50m\100
So 50m\100 =3500 so m = 7000
Question 1 : After deduction 20% from a certain sum , and then 30% from remainder , there is 3500 left . Find the original sum ?

Question 3 :Method Of Taking L.C.M Of decimal numbers ?
9*15=135 days divide 700 by 135 so , 700/135 =5.18 (Ignore decimal) so answer is 5 years.

Hi Zeeshan,
I've moved your thread to the Help Me ! forum.
This is not a huge topic , only review of concept of putting zero when divide by larger number such as 3/42 etc .This little thing is not given in mif
By using long division..
By division method

If the price is x then a discount of 10% means it will now cost 0.9x and then multiply by a further 0.85 to apply the second discount.
Bob
If the discount is 10% then how it costs 0.9x?
