The s,p,d,f configuration for cobalt (Co) is 1s22s22p63s23p64s23d7, determined by the position of the element on the periodic table. The electron configuration for Cobalt at ground state would simply be Co: [Ar] 4s²3d⁷.

The electron configuration of Cobalt will end in d block as Cobalt is an inner transition metal. Cobalt is in the 7th column of the d block and therefore has 7 d electrons d7.

In India, Tropical Moist Deciduous Forest occupies the largest area. The tropical monsoon deciduous forests are found in areas receiving annual rainfall of 100 to 200 cms in India, with a distinct dry and rainy seasons and a small range of temperature. They occur on the wetter western side of the Deccan Plateau, the north-eastern part of the Deccan Plateau and the lower slopes of the Himalayas, on the Siwalik Hills from Jammu in the west to West Bengal in the east.

They cover parts of Chhattisgarh, Orissa, Bihar, Jharkand, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu.

The ratio of A & B investments = (3x8 + 2x4):(4x8 + 5x4)

=> 8:13

=> 8/21 x 630 = 240.

A computer system consists of a computer case, a power supply unit, a motherboard, a central processing unit (CPU), main memory, and a hard disk drive.

Input devices include a keyboard, mouse, microphone, video camera, and image scanner.

Output devices include a monitor, speakers, and a printer.

SP of first article = Rs.1000

Profit = 20%

 CP = SP x 100100+P% = Rs. 25003

SP of Second Article = Rs.1000

 Loss = 20%

 CP = SP x 100100-L% = Rs. 1250

So, Total SP = Rs.2000; Total CP = Rs.6250/3

As the CP is more than SP, he makes a loss.

Loss = CP - SP = (6250/3) - 2000 = Rs.(250/3)

So, Loss Percent = Lossx100/CP = 4%
