SOLUTION:


1. 1;
Total number of students

2. 4;
CP of the article
5000*75/100*90/100+5000=38750
∴ Profit percentage
(50000-38750)/38750 * 100
== 29.03% gain

3. 5;
Five years ago the average age of 4 boys = 9 years
The present average age of 4 boys = 9+5 = 14
So the present age of new boys = 15 + 4 x 1 = 19 years

4.





Units of work done in 3 days = (2 + 3 + 4) = 9
∴ 72 units of work will be done in = 3 x 8 = 24 days


5. 3;
SP = 100, SP (with tax) = 130
New SP = 100 - 5 = 95
Effective discount = 130 - 95 = 35
So, when SP of 95, discount = 35
And when SP of Rs. 16,150, discount = 35/95x16150 = Rs. 5950

6. 5;
Initial ratio of water to wine = 40 : 10 = 4: 1
Final ratio of water to wine = (4 : 1) = 24:6
Required, final ratio of water to wine
= 60 : 40
= (6 : 4)
= 24 : 16x⁴
If total mixture is 40 litres, mixture replaced is = 10 litres
Here total mixture is 50 litre, mixture replaced is = 12.5 litres
