##### 3. Question

There are two circles of different radii. The are of a square is 784 sq cm and its side is twice the radius of the larger circle. The radius of the larger circle is seven – third that of the smaller circle. Find the circumference of the smaller circle.

CorrectLet the radii of the larger and the smaller circles be l cm and s cm respectively. Let the side of the square be a cm.

a^{2}= 784 = (4)(196) = (2^{2}).(14^{2})

a = (2)(14) = 28

a = 2l, l = a/2 = 14

l = (7/3)s

Therefore s = (3/7)(l) = 6 Circumference of the smaller circle = 2∏s = 12∏ cm.IncorrectLet the radii of the larger and the smaller circles be l cm and s cm respectively. Let the side of the square be a cm.

a^{2}= 784 = (4)(196) = (2^{2}).(14^{2})

a = (2)(14) = 28

##### 7. Question

Anil spends 40% of his income on rent, 30% of the remaining on medicines and 20% of the remaining on education. If he saves Rs. 840 every month, then find his monthly salary?

CorrectLet’s Anil’s salary be Rs. 100.

Money spent on Rent = 40% of 100 = Rs. 40.

Money spent on medical grounds = 30% of (100 – 40) = 3/10 * 60 = Rs. 18.

Money spent on education = 20% of (60 – 18) = 1/5 * 42 = Rs. 8.40

Anil saves 100 – (40 + 18 + 8.40) i.e., Rs. 33.60

Let us say 70 men take x days to consume 150 kg.

Quantity consumed by each item in x days = (7x/30) kg

Quantity consumed by 70 men in x days = (7/30 x)(70) kg

= (7/30 x) * (70) = 960

x = 60 days.IncorrectRate of consumption of each man = 1050/(150 * 30) = 7/30 kg/day

Let us say 70 men take x days to consume 150 kg.

Quantity consumed by each item in x days = (7x/30) kg

Quantity consumed by 70 men in x days = (7/30 x)(70) kg

= (7/30 x) * (70) = 960

x = 60 days. - Question 17 of 50

##### 40. Question

A person purchases 90 clocks and sells 40 clocks at a gain of 10% and 50 clocks at a gain of 20%. If he sold all of them at a uniform profit of 15%, then he would have got Rs. 40 less. The cost price of each clock is:

CorrectLet C.P. of clock be Rs. x.

Then, C.P. of 90 clocks = Rs. 90x.

[(110% of 40x) + (120% of 50x)] – (115% of 90x) = 40

44x + 60x – 103.5x = 40

0.5x = 40 => x = 80IncorrectLet C.P. of clock be Rs. x.

Then, C.P. of 90 clocks = Rs. 90x.

##### 48. Question

150 men consume 1050 kg of rice in 30 days. In how many days will 70 men consume 980 kg of rice?

CorrectRate of consumption of each man = 1050/(150 * 30) = 7/30 kg/day

Let us say 70 men take x days to consume 150 kg.

Quantity consumed by each item in x days = 7x/30 kg.

Quantity consumed by 70 men in x days = (7x/30)(70)kg

(7x/30)(70) = 980

x = (980 * 30)/490 => x = 60 daysIncorrectRate of consumption of each man = 1050/(150 * 30) = 7/30 kg/day

Let us say 70 men take x days to consume 150 kg.

Quantity consumed by each item in x days = 7x/30 kg.

Quantity consumed by 70 men in x days = (7x/30)(70)kg
