A stationery seller has a highlighter pen, a country map, and a world map. The cost of a highlighter pen is Rs. 96. If he sells a pen with a country map, he receives the amount twice the value of the world map. And if he sells a pen with the world map, he receives an amount that is less than the value of the country map by Rs. 210. What is the value of the world map?

Option 1 : Rs. 402

Given:

The cost of a highlighter pen is Rs. 96.

Calculation:

Let the value of country map be a and, let the value of the world map be b

According to statement,

96 + a = 2b and 96 + b = a – 210

⇒ 2b = 96 + a, 2b = 2a – 420 – 192

⇒ 96 + a = 2a – 420 – 192

⇒ a = 708

Value of country map = Rs. 708

∴ Value of world map = 1/2 × = Rs. 402

Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.?

Option 2 : Only 3Concept:  DC power is more energy-efficient than AC power. DC Motors and appliance have higher efficiency and power to size characteristics. DC-based lighting (LED) is as much as 75% more efficient than...
