Andre45 [30]

The principal money Mrs Karki deposited in the bank was

= Rs 1339

Simple interest (Si) received = Rs 4,740

Time (t)= 6 years

Rate (r)= 59%

Therefore the principal amount (p) =

p = \frac{si \times 100}{r \times t}

where,

p =  \frac{4740 \times 100}{59 \times 6}

p =  \frac{474000}{354}

p = 1339

Therefore, the principal money Mrs Karki deposited in the bank was = Rs 1339

sweet-ann [11.9K]

Answer:

Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6

Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.

When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.

Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
