Let the present age of A = x, Present age of B = 76-x
ATQ,
x+8 = 76-x+14
2x = 82
x =41
Present age of A = 41
Age of A 15 years from now = 41+15 = 56 years

The perimeter of rectangle A is 96cm, where the difference in length and breadth is 8cm. Area of rectangle B is 30% more than the area of rectangle A. Find the area of rectangle B.

Correct

Answer: 1) 728 sq cm
Explanation:
Let the Breadth = x and length = x+8
Perimeter = 2*(x+x+8)
2*(x+x+8) = 96
2x+8 = 48
x =20
x+8 = 28
Area of rectangle A = 20*28
Area of rectangle B = 130% of 20*28 = (130/100)*20*28 = 728

Incorrect

Answer: 1) 728 sq cm
Explanation:
Let the Breadth = x and length = x+8
Perimeter = 2*(x+x+8)
2*(x+x+8) = 96
2x+8 = 48
x =20
x+8 = 28
Area of rectangle A = 20*28
Area of rectangle B = 130% of 20*28 = (130/100)*20*28 = 728

A sum of Rs. 1200 is lent at the beginning of a year at a certain rate of interest. After 8 months, a sum of Rs. 400 more is lent but at the rate thrice the former. At the end of the year, Rs. 80 is earned as interest from both the loans. What was the original rate of interest?

Correct

Answer: 2) 5%
Explanation:
SI = (P*R*T)/100
From the question it is clear that 1200 is lent for 12 months and 400 is lent for (12-8) = 4 months
Let the Rate of interest for 1200 is R, the rate of interest for 400 is 3R
ATQ,
(1200*R*1)/100 + (400*3R*4) /12*100 = 80
12R + 4R = 80
16R = 80
R = 5%

Incorrect

Answer: 2) 5%
Explanation:
SI = (P*R*T)/100
From the question it is clear that 1200 is lent for 12 months and 400 is lent for (12-8) = 4 months
Let the Rate of interest for 1200 is R, the rate of interest for 400 is 3R
ATQ,
(1200*R*1)/100 + (400*3R*4) /12*100 = 80
12R + 4R = 80
16R = 80
R = 5%

Correct

Answer: 1) Rs. 3900
Explanation:
28% on food
Amount left = 100-28 = 72%
On education = 1/3 of 72 = 24%, on travel = 1/4 of 72 = 18%
ATQ,
24%-18% = 780
6% = 780
1% = 130
The sum 100% = 13000
Saving = 100-(28+24+18) =30% = 130*30 = 3900

Incorrect

Answer: 1) Rs. 3900
Explanation:
