Possible arrangements for 4 books are 4x3x2x1 = 24
For making a new arrangement, two books are required to be moved.
One book takes one minute, then for 2 books

In high plateaus of the Hot  Wet Equatorial Region the temperature is very much lower and so the "Ecuador type' of climate develops typically on the high plateau of Ecuador at an elevation of about 2430 to 3050 meter. Because of the pleasant average temperature of, 13oC. This is described as the "Land of eternal spring".

Here the given series 7  18  42  94  204 follows a pattern that, 

7

7 ×2+4 = 18

18 ×2+6 = 42

42 ×2+10 = 94

94 ×2+16 = 204

Similarly,

4

4 ×2+4 = 12

12 ×2+6 = 30

30 ×2+10 = 70

70 ×2+16 = 156

Hence, the value of P = 156.

The given statement is True.

Ketchup is acidic, having a pH of 3.9. The acidic component, acetic acid, will react with the metal tin. This reaction will result in a metal acetate that will contaminate the ketchup.

Hence, The acetic acid in the ketchup will react with the metal tin, forming a metal acetate that will pass into the ketchup which leads to its contamination.

Warm, moist climate (with a temperature of 180 C- 270C and well-distributed rainfall between 125 to 200 cms) and deep, loamy, well-drained soil made of weathered lava are most suitable for the cultivation of coffee. However,  Brazil is a quantity producer and not a quality producer.

Now, the principal amount P = Rs. 1,45,440

Rate of interest R = 20%/annum

Now monthly income I = PTR/100 = 1,45,440 x 20 x 1/100 x 12

= 2908800/1200

= Rs. 2424.

Hence, her monthly income = Rs. 2424.
