Answers
Answer:
Lyophobic colloids are liquid hating colloids (Lyo means solvent and phobic means hating). When these colloids are mixed with the suitable liquid, a very weak force of attraction exists between colloidal particles and liquid and system does not pass into colloidal state readily.
Answer:
Solution:
Given
Principal (p) = Rs50000
Rate of interest (r) = 8% p.a
Let the amount at the end of the second year = A
\boxed{Amount = p\times(1+\frac{r}{100})^{n}}
Amount=p×(1+
100
r
)
n
i)
Let the number of times interest paid in 2 years ( n)=2
A = 50000[1+8/100]²
= 50000 × (108/100)²
= 5×108×108
= Rs58320
Therefore,
The amount standing to her
credit at the end of the second
year (A) = Rs58320
ii ) Finding interest for third year:
P = Rs 58320,
R = 8%
T = 1 year
Simple Interest (I) = (PTR)/100
= ( 58320 × 1 × 8 )/100
= Rs 4665.60
