Maharashtra Board 7th Maths Chapter 10, Class 7 Maths Chapter 10 solutions

Question 1.
If the interest on Rs 1700 is Rs 340 for 2 years, the rate of interest must be__.
(A) 12%
(B) 15%
(C) 4%
(D) 10%
Solution:
(D) 10%

Hint:
∴ Total interest =P×R×T100
∴ 340=1700×R×2100
∴ R = 10%

Question 2.
If the interest on Rs 3000 is Rs 600 at a certain rate for a certain number of years, what would the interest be on Rs 1500 under the same conditions?
(A) Rs 300
(B) Rs 1000
(C) Rs 700
(D) Rs 500
Solution:
(A) Rs 300

Hint:
The interest on Rs 3000 at certain rate of interest is Rs 600.
Let us suppose the interest on Rs 1500 at the same rate is x.
∴ 6003000=x1500
∴ x = Rs 300

Question 3.
Javed deposited Rs 12000 at 9 p.c.p.a in a bank for some years, and withdrew his interest every year. At the end of the period, he had received altogether Rs 17,400. For how many years had he deposited his money?
Solution:
Here, P = Rs 12000, R = 9 p.c.p.a and amount = Rs 17400
Amount = Principal + Interest
∴17400 = 12000 + Interest
∴Interest = 17400 – 12000 = Rs 5400
∴ Total interest =P×R×T100
5400=12000×9×T100
∴ 5400×10012000×9=T
∴ T = 5 years
∴ Javed had deposited the amount for 5 years.

Question 4.
Lataben borrowed some money from a bank at a rate of 10 p.c.p.a interest for 212 years to start a cottage industry. If she paid Rs 10250 as total interest, how much money had she borrowed?
Solution:
Here, R = 10 p.c.p.a, T = 2.5 years, I = Rs 10250

∴ P = Rs 41000
∴ Lataben had borrowed an amount of Rs 41000 from the bank.

Question 5.
Fill in the blanks in the table.

	Principal	Rate of interest (p.c.p.a.)	Time	Interest	Amount
i.	Rs 4200	7%	3 years
ii.		6%	4 years	Rs 1200
iii.	Rs 8000	5%		Rs 800
iv.		5%		Rs 6000	Rs 18000
v.		212 % 2	5 years	Rs 2400

Solution:
i. Total interest =P×R×T100
= 4200×7×3100
= Rs 882
Amount = Principal + interest
= 4200 + 882
= Rs 5082

ii. Total interest =P×R×T100
∴ 1200=P×6×4100
∴ 1200×1006×4=P
∴ P = Rs 5000
Amount = Principal + interest
= 5000 + 1200
= Rs 6200

iii. Total interest =P×R×T100
∴ 800=8000×5×T100
∴ 800×1008000×5=T
∴ T = 2 years
Amount = Principal + interest
= 8000 + 800
= Rs 8800

iv. Amount = Principal + interest
∴ 18000 = Principal + 6000
∴ Principal = Rs 12000
Total interest =P×R×T100
∴ 6000=12000×5×T100
∴ 6000×10012000×5=T
∴ T = 10 years

v. R = 212 % = 2.5 %
∴ Total interest =P×R×T100
∴ 2400=P×2.5×5100
∴ 2400=P×25×5100×10
∴ 2400×10×10025×5=P
∴ P = Rs 19200
Amount = Principal + interest
= 19200 + 2400
= Rs 21600

	Principal	Rate of interest (p.c.p.a.)	Time	Interest	Amount
i.	Rs 4200	7%	3 years	Rs 882	Rs 5082
ii.	Rs 5000	6%	4 years	Rs 1200	Rs 6200
iii.	Rs 8000	5%	2 years	Rs 800	Rs 8800
iv.	Rs 12000	5%	10 years	Rs 6000	Rs 18000
v.	Rs 19200	212 % 2	5 years	Rs 2400	Rs 21600
