As it is given that a18 − a14 = 32 (a + (18-1)d) - (a + (14-1)d) = 32 a + 17d - a - 13d = 32 4d = 32 d = 8 Hence required common difference is 8.... read more

As an = a + ( n − 1 ) d According to given values 4 = a + (7 − 1) (− 4) 4 = a + 6 (− 4) 4 + 24 = a  a = 28 , Hence first term a is 28... read more

Here first term a = p and common difference d = q As a10 = a + ( 10 − 1 )d a10 = p + 9q So 10th term is (p + 9q)... read more

Since 2x, (x+10) and (3x+2) are in AP we obtain, (x + 10) − 2x = (3x + 2) − (x + 10) -x + 10 = 2x -8 -x - 2x = -8 -10 -3x = -18 x = 6 Hence answer is x = 6 ... read more

Exchange of gases in tissues occurs through diffusion. Oxygen is carried as oxyhaemoglobin from lungs to tissues. It dissociates and carbon dioxide diffuses out into blood from tissues. It is transpor... read more

Total number of cards is 52 So n(S) = 52 Total number of red king is 2 So n(E) = 2 The  probability  of  getting a red king P(E) = n(E)/n(S) P = 2/52 = 1/26 Hence answer is 1/26... read more

Total number of cards is 52 So n(S) = 52 Total number of black king is 2 So n(E) = 2 The  probability  of  getting a black king P(E) = n(E)/n(S) P = 2/52 = 1/26 Hence answer is ... read more

Total number of eggs is 400 So n(S) = 400 Let a is the total number of bad egg So n(E) = a Probability of getting bad egg is 0.035 So P(E) = 0.035 As P(E) = n(E)/n(S) So 0.035 = a/400 a = 40... read more

Total number of sold tickets are 6000. So n(S) = 6000 Let she bought x tickets So n(E) = x Probability of winning the first prize in a lottery is 0.08 So P(E) = 0.08 As P(E) = n(E)/n(S) So 0.... read more
