The sum of A, B and C is 3800.If A is one third of B and B is onefifth of C, then C is equal to O

Solution
A=^{1}⁄_{3}B and B=^{c}⁄_{5}
∴A=^{1}⁄_{3}B=^{1}⁄_{3}×^{C}⁄_{5}=^{C}⁄_{15}
∴A+B+C=3800
⇒^{C}⁄_{15}+^{C}⁄_{5}+C=3800
⇒\(\frac{C+3C+15C}{15}=3800\)
⇒19C=3800×15
⇒C=\(\frac{3800\times 15}{19}=3000\)
The single discount equivalent to three successive discounts of 100%,200% and 25%, is

Solution
Let listed Price=₹100
Total discounted price after successive discounts of 10%,20% & 25%
\(=100\times \frac{10010}{100}\times \frac{10020}{100}\times \frac{10025}{100}\)
\(=100\times\frac{90}{100}\times \frac{80}{100}\times \frac{75}{100}\)
\(=\frac{5400}{100}=₹54\)
