Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Let the two numbers be a and b respectively and the third number be c.
\na = 1.3c
\nb = 1.75c
\n$\\frac{a}{b}$ = $\\frac{1.3}{1.75}$
\n=> a : b = 26 : 35<\/p>\n

2)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

R=S + 4….(1)<\/p>\n

also (R+4)\/(S+4)=9\/8….(2)<\/p>\n

On solving (1) and (2) we get R=32 and S=28.<\/p>\n

\u2234 Ravi’s age 15 years ago will be 17<\/p>\n

3)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let the ages today be 4x and 3x. Ages four years from now are 4x + 4 and 3x + 4<\/p>\n

But 4x+4:3x+4 = 9:7<\/p>\n

So, x = 8<\/p>\n

So, their current ages = 32 and 24<\/p>\n

Let them be married for x years<\/p>\n

Age at marriage = 32 – x and 24 – x<\/p>\n

But 32 – x : 24 – x = 13: 9<\/p>\n

So \u00a0x = 6 years.<\/p>\n

4)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let the fourth number be x and first three numbers be a, b and c respectively.
\na = 1.6x, b = 2.4x and c = 4.8x
\na : b : c = 1.6x : 2.4x : 4.8x = 2 : 3 : 6<\/p>\n

5)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Let the ages of the father and child be 6x and x respectively.
\n6x+x = 28
\n7x = 28, x = 4
\nAges of the father and child are 24 years and 4 years respectively.
\nAges of the father and child 6 years later are 30 years and 10 years.
\nRatio = 30:10 = 3:1<\/p>\n
