A device which is used to convert light energy directly into electrical energy is called as photovoltaic cell or a solar cell.

A thermocouple is a device for measuring temperature.

Let Rs. K invested in each scheme

Two years C.I on 20% = 20 + 20 + 20x20/100 = 44%

Two years C.I on 15% = 15 + 15 + 15x15/100 = 32.25%

Now,

(P x 44/100) - (P x 32.25/100) = 528.75

=> 11.75 P = 52875

=> P = Rs. 4500

Hence, total invested money = P + P = 4500 + 4500 = Rs. 9000.

Latitude comes first among latitude or longitude. 

Latitude is written before longitude. The first number is always the latitude and the second is the longitude.

Latitude is written with a number, followed by either “north” or “south” depending on whether it is located north or south of the equator. Longitude is written with a number, followed by either “east” or “west” depending on whether it is located east or west of the Prime Meridian.

In the given puzzle, the logic is

2 + 3 = 10 => (2 + 3) * 2 = 10

6 + 3 = 54 => (6 + 3) * 6 = 54

8 + 3 = 88 =>  (8 + 3) * 8 = 88

Similarly,

9 + 7  => (9 + 7) * 9 = 16 x 9 = 144.

Luanda, the capital of Angola, has topped the list of most expensive cities for expatriates, according to Mercer’s 23rd annual Cost of Living Survey.

Mercer’s authoritative survey is one of the world’s most comprehensive, and is designed to help multinational companies and governments determine compensation allowances for their expatriate employees.

M = 10 days

The ratio of efficiency of M & N are 3 : 2

Hence, the time rquired for N alone = 15 days

=> Required time taken t=by both to complete the work = M x N / M + N 

= 10 x 15/ 10 + 15

= 150/25

= 6 days.
