View Answer

Answer: a
Explanation: Let the total value of business be Rs.x.
Then, \(\frac{1}{3} \, of \, \frac{1}{2}\) of x=55000 🡪 \(\frac{1}{3}*\frac{1}{2}\)*x=55000 🡪 x = Rs.330000.

6. A man spends 2/7th of his salary on house rent, 5/12th of his salary on food and 1/6th of his salary on conveyance. If he has Rs.2200 left with him. Find his expenditure on food.

Explanation: Let the monthly salary be Rs.x.
Part of the salary left = x-\(\Big(\frac{2}{7}-\frac{5}{12}-\frac{1}{6}\Big)x=\frac{11x}{84}\).
Then, \(\frac{11x}{84}\)=2200 🡪 x = 16800.
Hence, expenditure on food = \(\frac{5}{12}\)*16800=Rs.7000.

7. A fourth of Ajay’s marks in Mathematics exceeds a fourth of his marks in English by 10. If he got 280 marks in the two subjects together, how many marks he got in mathematics?

Then, \(\frac{1}{4}\) x – \(\frac{1}{4}\)y=10 🡪 x-y=40 …… (i)
x+y=280…… (ii)
Solving (i) and (ii), we get, x = 160 and y = 120.
Therefore, Ajay’s marks in mathematics is 160.

8. If 1/8th of a pencil is black, 1/4th of the remaining is white and the remaining 5.25 cm is grey, find the total length of the pencil.
a) 6 cm
b) 12 cm
c) 10 cm
d) 8 cm
View Answer

Answer: d
Explanation: Let the total length of the pencil be x cm.
Black part = (x/8) cm. Remaining part = (x – x/8) = (7x/8) cm.
White part = \(\frac{1}{4}*\frac{7x}{8}=\frac{7x}{32}\) cm. Remaining part = \(\frac{7x}{8}-\frac{7x}{32}=\frac{21x}{32}\)cm.
\(\frac{21x}{32}\)=5.25 🡪 x = 8 cm
Hence, the total length of the pencil is 8 cm.
