How many two digit number is divisible by 3 and arithmetic progression

Answer»

Let two DIGIT numbers are 10, 11, 12 , -------------99

which are DIVISIBLE by 3 are 12, 15 ...............,99.

Here a = 12 and common dofference = 3 , an = l = 99

nth term (tn) = a + ( n - 1) d

⇒ 99 = 12 + ( n - 1) 3

⇒ (n - 1)3 = 99 - 12 = 87

⇒ ( n -1) = 87 / 3

⇒ n - 1 = 29

∴ n = 30

∴  30 two digit numbers which are divisible by 3.

A person invests 5000 for 3 years at a certain rate of interest compounded annually. at the end of two years this amounts to 6272. calculate rate of interest per annum

Answer»

A SUM P, compounded annually will AMOUNT to A, which can be given by the formula,

A = P[1+r/100]^n, where r is the rate of interest and n is the compounding duration.

In this case, A = Rs. 6272, P = Rs. 5000, n = 2 and r needs to be found out.

Thus, 6272 = 5000[1+r/100]^2

or 6272/5000 = (1+r/100)^2

1+r/100 = SQRT (6272/5000) = sqrt (1.2544) = 1.12

Therefore, r/100 = 1.12-1 = 0.12

Or, the rate of interest is 12%.

The amount at the end of the THIRD year is

A = 5000[1+12/100]^3 = 5000*1.404928 = Rs. 7024.64

Thus, the rate of interest, r = 12% and amount at the end of 3 years would be Rs. 7024.64

Fin d the value of a when ay²-9y+4a is divided by 2y-1 gives the remainder 5upon 6

Answer» GIVEN that (2y - 1) is the factor the given equation which leaves REMAINDER 5/6


By Remainder Theorem,

f(y) = f(1/2)

HENCE,



a {(y)}^{2} - 9y + 4a = \frac{5}{6} \\ \\ \\ a {( \frac{1}{2}) }^{2} - 9( \frac{1}{2} ) + 4a = \frac{5}{6} \\ \\ \\ \\ \frac{a}{4} - \frac{9}{2} + 4a = \frac{5}{6} \\ \\ \\ => \frac{a - 18 + 16a}{4} = \frac{5}{6} \\ \\ \\ => \frac{17a - 18}{4} = \frac{5}{6} \\ \\ \\ => 102a - 108 = 20 \\ \\ \\ \\ = > 102a = 20 + 108 \\ \\ => 102a = 128 \\ \\ \\ \\ => a = \frac{128}{102} \\ \\ \\ a = \frac{64}{51}

The diameter of the Sun is 1.4 × 109 m and the diameter of the earth is 1.2756 × 107 m. Compare the diameter of the earth with the diameter of the sun.

Answer»

Hi there

Your answer is :-


Given that Diameter of the Sun is 1.4 x 10^9 meters and Earth is 1.2768 x 10^7 meters.

Ratio of diameters of the sun to that of earth is = 1.4 x 10^9 : 1.2768 x 10^7

= 1.4 x 10^2 : 1.2768

= 140 : 1.2768.

= 70 : 0.6384

= 35 : 0.3192 (MULTIPLY 1000 each TERM)

= 35000 : 3192

= 17500 : 1596

= 87500 : 798

= 43750 : 399 ( Ans )
