The ^@L.C.M.^@ and ^@H.C.F.^@ of marks scored by Ikhlaas and Spectra in a math test are ^@ 3510 ^@ and ^@ 20 ^@ respectively. If Spectra's score is ^@ 135, ^@ what is Ikhlaas's score?
In a two digit number,its unit's digit is 4 more than ten's digit. If sum of this number and the number obtained by reversing the order of its digits is 132, find the number.
Find the area of the triangle formed by joining the midpoints of the sides of the triangle whose vertices are ^@ A(12,-2)^@, ^@B(8,6)^@, and ^@C(16,10)^@.
In the given figure, a circle is inscribed in a ^@ \triangle PQR.^@ ^@ PQ = 9 \space cm, QR = 7 \space cm, ^@ and ^@ PR = 11 \space cm.^@ What is the length of ^@QM^@ ?
An umbrella has ^@6^@ ribs which are equally spaced as given in the figure. Assuming the umbrella to be a flat circle of radius ^@ 29 \space cm^@, find the area between two consecutive ribs of the umbrella.^@ \bigg[ \pi = \dfrac { 22 } { 7 } \bigg]^@
Gemma and his wife are busy in making jaggery out of sugarcane juice. They have processed the sugarcane juice to make the molasses which are poured into the moulds of the shape shown in the figure. It will be cooled to solidify in this shape to be sent to the market. Each mould is in the shape of a frustum of a cone having the radii of its two circular faces as ^@21 \space cm^@ and ^@33 \space cm^@ and the height of the mould is ^@18 \space cm^@. If each ^@ cm^3 ^@ of molasses weighs about ^@ 2 \space gm ^@, find the weight of molasses that can be poured into each mould. (Take ^@ \pi = \dfrac { 22 } { 7 } ^@)
