Two numbers are in the ratio $4 : 5$ and their L.C.M is $180$. The smaller number is :

Two numbers are in the ratio $4 : 5$. If the first number is increased by $20\%$ and the second is decreased by $20\%$, what will be the ratio of the new numbers?

When a particular number is subtracted from each of $7, 9, 11$ and $15$, the resulting numbers are in proportion. The number to be subtracted is:

The angles of a triangle are in the ratio $1:2:3$. The greatest angle of the triangle is:

The monthly salaries of A, B and C are in the ratio $1:2:3$. If C's monthly salary is $₹1200$ more than that of A, then B's annual salary is:

The ratio of the ages of Meena and Meera is $4:3$ and the sum of their ages is $28$ years. The ratio of their ages after $8$ years will be:

The salaries of A, B and C are in the ratio $1:3:4$. If these salaries be increased by $5\%, 10\%$ and $15\%$ respectively, then the increased salaries will be in the ratio:

A boy has a few coins of $50, 25$ and $10$ paise in the ratio $1:2:3$ respectively. If the total amount of the coins is $₹6.50$, then, the number of $10$ paise coins is:

$₹2010$ are to be divided among A, B and C in such a way that, if A gets $₹5$, then B gets $₹12$, and if B gets $₹4$, then C must get $₹5.50$. The share of C will exceed that of B by:
