If 4 is subtracted from each, they become 3 : 5. The numbers areDivision of Rs.324 between X and Y in the ratio 11 : 7 gives themThe angles of a triangle are in the ratio 2 : 7 : 11. The angles areThe ratio compounded of 2 : 3, 9 : 4, 5 : 6 and 8 : 10 isIf p : q = 2 : 3 and x : y = 4 : 5, the value of (5px + 3qy) : (10px + 4qy) isThe number which when subtracted from each term of the ratio 19 : 31 reduces it to 1 : 4 isThe ratio of two numbers is 7 : 10 and their difference is 105. The numbers areIf 6 : x : : x : 24, then x equalsDaily earnings of two persons are in ratio 4 : 5 and daily expenses in ratio 7 : 9. If each saves Rs.50, theirIf x : y = 3 : 4, the value of (x^2*y + x*y^2) : (x^3 + y^3) isThe ratio compounded of 4 : 9 and the duplicate ratio of 3 : 4 isP, Q, R are three cities. Avg temp of P : Q is 11 : 12, and P : R is 9 : 8. Avg temp of Q : R isThe value of log(8) base 2 isThe value of log(1/64) base 4 isIf log x = log 5 + 2 log 3 - log 9, then x equalsIf 2^x = 8, then x equalsThe value of log(75/16) - 2 log(5/9) + log(32/243) isIf a^x = b^y = c^z and b^2 = ac, then 1/x + 1/z equalsIf x = (sqrt(3) + 1) / (sqrt(3) - 1) and y = 1/x, then x^2 + y^2 equalsIf log(2) = 0.3010, the number of digits in 5^20 isIf a, b, c, d are in proportion (a : b :: c : d), then by componendo and dividendo, (a + b)/(a - b) equalsThe inverse ratio of 11 : 15 isThe duplicate ratio of 3 : 4 isThe value of x^(a-b) * x^(b-c) * x^(c-a) for any non-zero x isIf a : b = c : d, then by alternendo, the relation a : c = b : d meansIf log a equals zero, the value of a isThe mean proportional between 4 and 16 equalsIf 25% of a number plus 15 equals 40, the number is
